	(Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
	Is_Remote_Call_Interface to identify RACW types in a stable and

	(Collect_Interps): When only one interpretation has been found, set N's
	Entity and Etype to that interpretation, otherwise Entity and Etype may
	still refer to an interpretation that was ignored by Add_One_Interp,
	in which case would end up with being marked as not overloaded but with

	* a-tags.adb:
	(Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
	 indirection added to the HT_Link component of the TSD. This is required
	 to statically allocate the TSD.

	* a-tags.ads:
	Minor reordering of the declarations in the private part. Required to
	add a level of indirection to the contents of the TSD component HT_Link.
	This is required to statically allocate the TSD.

	* decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
	Is_Statically_Allocated set from constant objects.
	Do not make exported constants created by the compiler volatile.
	(gnat_to_gnu_param): Do not treat an IN parameter whose address is taken

	before returning them.

	* exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
	public part of the package.
	(Make_DT): Move HT_Link component out of the TSD record. For this
	purpose Make_DT now declares a separate object that stores the
	HT_Link value, and initializes the TSD component with the address
	of this new object. The addition of this level of indirection is
	required to statically allocate the TSD because the TSD cannot
	have variable components.
	(Expand_Interface_Conversion): Improve the expanded code.
	(Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.

	* sem_disp.adb (Check_Dispatching_Operation): In case of a body

	be built at the end of the library package; otherwise we notify that
	we cannot build the static dispatch table.

	of errors in the documentation in this regard).

	* exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.

	* exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
	of these procedures are passed a function call that already has
	build-in-place actuals (testing new flag
	Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
	the case where processing continues.
	(Expand_Call): If the call is generated from a thunk body then we
	propagate the extra actuals associated with the accessibility
	level of the access type actuals.

	* sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
	of each extra formal of a protected operation to reference the
	corresponding extra formal of the subprogram denoted by the

	(Uninstall_Declarations): If entity is a use-visible compilation unit,
	its child units are use-visible only if they are visible child units.

	* sem_util.adb (Is_Preelaborable_Expression): New function to determine
	whether an expression can be used within a type declaration that
	requires preelaborable init.
	(Check_Components): Replace inline code that does partial checking for
	preelaborable default expressions with call to
	Is_Preelaborable_Expression.
	(Has_Preelaborable_Initialization): In the case of a generic actual
	subtype, (that is, Is_Generic_Actual is True), return the result of
	applying Has_Preelaborable_Initialization to the generic actual's base
	type.

	* g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
	call to Jan_1_Day _Of_Week to optimize its performance.
	(Is_Leap): Move the routine to the scope of Week_In_Year.
	(Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
	weekday on which January 1 falls of Year - 1 and Year + 1. This function
	avoids calling Time_Of and Split, thus making it more efficent.
	(Week_In_Year): Reimplemented in oder to follow ISO 8601.

	* g-calend.ads (Week_In_Year): Change comment to reflect new
	implementation.

	* g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
	Command_Line): New types
	(Define_Alias, Define_Prefix, Free): New subprograms. These provide
	support for defining how switches can be grouped on a command line (as
	is the case for -gnatw... for GNAT), and how simple switches can be
	used as aliases for more complex switches (-gnatwa is same as
	-gnatwbcef...)
	(Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
	(Start, Current_*): New subprograms
	Added support for parsing an array of strings in addition to the real
	command line.
	(Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
	 be moved from the body to the private part of the spec.
	(*): All subprograms now have an extra parameter with default value to
	specify which parser should be used. For backward compatibility, it
	defaults to parsing the command line of the application. They were also
	modified to properly handle cases where each of the argument does not
	start at index 1 (which is always true for Ada.Command_Line, but not
	when processing any Argument_List).
	(Free): New subprogram
	(Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
	Argument): New subprograms
	(Switch_Parameter_Type): New enum, which clarifies the code. The extra
	special characters like ':', '=',... are now handled in a single place,
	which makes the code more extensible eventually.
	(Getopt, Full_Switch): When the switch was returned as part of the
	special character '*', make sure it is prepended by the switch character
	('-' in general), so that the application knows whether "foo" or "-foo"
	was specified on the command line.

2007-09-26  Florian Villoing  <villoing@adacore.com>

	* g-dirope.adb (Remove_Dir): In case we are removing directories

	value before propagating the exception.

2007-09-26  Vincent Celier  <celier@adacore.com>

	* gnatbind.adb: If there are several ALI files specified and there is

	no longer used.

	* prj-attr.adb: New attributes Required_Switches (<language>) in
	packages Compiler and Binder.

	attributes for gprbuild. No impact on GNAT tools.

	* prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer

	create an abstract subprogram in the case of 'Input. For 'Output we now

	(Predefined_Primitive_Bodies): Now allow the creation of a predefined
	body for 'Output when the type is abstract (only the creation of the
	body for 'Input is excluded when the type is abstract).

	associated tagged type is an abstract extension. Add comments for
	return statement.
	(Expand_N_Object_Declaration): For the case of a shared passive
	variable, insert init proc call only after the shared variable
	procedures have been processed, because the IP call needs to undergo
	shared passive variable reference expansion, which requires these

	* sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,

	hidden.

2007-08-31  Hristian Kirtchev  <kirtchev@adacore.com>

	* restrict.adb, namet.adb, par-util.adb: Remove redundant type
	conversion.

	* sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect
	simple redundant qualifications. The check is performed whenever the
	expression is a non-overloaded identifier.
	(Resolve_Type_Conversion): Enchance the redundant type conversion check
	to include loop parameters.
	(Valid_Conversion): Avoid generation of spurious error message.

2007-08-31  Bob Duff  <duff@adacore.com>

	* par-ch4.adb (P_Simple_Expression): Fold long sequences of
	concatenations of string literals into a single literal, in order to
	avoid very deep recursion in the front end, which was causing stack
	overflow.

	* sem_eval.adb (Eval_Concatenation): If the left operand is the empty
	string, and the right operand is a string literal (the case of "" &
	"..."), optimize by avoiding copying the right operand -- just use the
	value of the right operand directly.

	* stringt.adb (Store_String_Chars): Optimize by growing the
	String_Chars table all at once, rather than appending characters one by
	one.
	(Write_String_Table_Entry): If the string to be printed is very long,
	just print the first few characters, followed by the length. Otherwise,
	doing "pn(n)" in the debugger can take an extremely long time.

	* sem_prag.adb (Process_Interface_Name): Replace loop doing
	Store_String_Char with Store_String_Chars.

	have not been fully analyzed.

2007-08-31  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
	flag, for effiency. It is called when analyzing arithmetic operators
	and also for actuals in calls that are universal_integers. The flag is
	set for the predefined type address, and for any type or subtype
	derived from it.

	* sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
	Universal_Integer, when the formal is a descendent of address and the
	call appears in user code.
	(Analyze_Selected_Component): if the prefix is a private extension, the
	tag component is visible.

	* sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an
	entity flag.

2007-08-31  Robert Dewar  <dewar@adacore.com>

	gnatpp '--separate-stmt-name' option.
	Add new qualifier /USE_ON_NEW_LIN for the new gnatpp '--use-on-new-line'
	option.

	* gnat_ugn.texi: Add description for the new gnatpp

2007-08-16  Gary Dismukes  <dismukes@adacore.com>

	* cstand.adb (Create_Standard): Create an entity for a zero-sized type
	associated with Standard_Debug_Renaming_Type, to be used as the type of
	the special variables whose names provide debugger encodings for
	renaming declarations.

	* einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
	(Set_Debug_Renaming_Link): Change to set Node25.
	(Write_Field13_Name): Remove case for E_Enumeration_Literal.
	(Write_Field25_Name): Add case for E_Variable to output
	"Debug_Renaming_Link".
	(Write_Field23_Name): Correct the output string for "Limited_View".

	* exp_dbug.adb: Add with and use of Tbuild.
	(Debug_Renaming_Declaration): Replace creation of an enumeration type

	    Ed Schonberg  <schonberg@adacore.com>
	    Javier Miranda  <miranda@adacore.com>

	* exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
	ancestor part given by an aggregate to test for an unchecked conversion,
	since this can occur in some cases when the ancestor part is a function
	call, and we don't want to fall into the recursive call to this
	procedure in that case.

	* exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
	stream attributes on limited types to account for user-specified
	attributes as well as whether Input (resp. Output) becomes available
	due to Read (resp. Write) being available for the type. Change Boolean
	variable to the more accurate name
	Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
	double-"not" predicate at beginning of return statement to more
	understandable form.

	* exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
	return has an associated N_Handled_Sequence_Of_Statements, then wrap it
	in a block statement and use that as the first statement of the
	expanded return rather than incorrectly using the handled sequence as
	the first statement.

	* exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
	operation, generate an explicit freeze node for it rather than
	generating extra formals, to ensure that gigi has the proper order of
	elaboration for anonymous subtypes in the signature of the subprograms.
	(Build_In_Place_Formal): Move assertion to beginning of loop.
	(Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
	applied to a function call (occurs for some cases of 'Input).
	(Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
	applied to a function call (occurs for some cases of 'Input).

	* exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
	2005, generate an extended return statement enclosing the result object
	and 'Read call.

	* freeze.adb (Freeze_Record_Type): Extend the current management of
	components that are access type with an allocator as default value: add
	missing support to the use of qualified expressions of the
	allocator (which also cause freezing of the designated type!)
	(Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
	dispatching operation, since extra formals may be needed by calls to
	build-in-place functions (such as stream 'Input).

	* sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
	formals for 'Constrained and accessibility level in the case of a
	predefined dispatching operation.

	* exp_util.adb (Insert_Actions): A protected body is a valid insertion
	point, no need to find the parent node.

2007-08-16  Javier Miranda  <miranda@adacore.com>

	* exp_attr.adb (Attribute_Priority): Add missing support for entries
	and entry barriers.

2007-08-16  Javier Miranda  <miranda@adacore.com>

	* exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
	is not really required and can introduce regression with the debugger.
	The original problem is fixed with the patch written for checks.adb.

2007-08-16  Thomas Quinot  <quinot@adacore.com>

	* g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

	(Gnatmake): For the compiler, call Test_If_Relative_Path with
	Including_Non_Switch set to False.

	* makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
	parameter Including_Non_Switch, defaulted to True. When
	Including_Non_Switch is False, options that are not switches and
	appear as relative path are not converted to absolute paths.

	* Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
	makefiles

	currently inspected is a selected component, retrieve the entity of
	its selector.
	(Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
	from the immediate ancestor of Main_Unit_Entity.
	(Install_Limited_Withed_Unit): Do not install the limited view of
	package P if P is reachable through an ancestor chain from package C
	and C also has a with clause for P in its body.
	(Has_Limited_With_Clause): New routine.
	(Has_With_Clause): New routine.

2007-08-16  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
	generic for an enclosing instance is a global reference, even though
	its scope is the enclosing instance.

2007-08-16  Gary Dismukes  <dismukes@adacore.com>
	    Javier Miranda  <miranda@adacore.com>

	* sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
	initialize a limited object.
	(Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4

	    Bob Duff  <duff@adacore.com>
	    Nicolas Setton  <setton@adacore.com>

	* sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
	(Resolve): Alphabetize local variables. Add new variable From_Lib. When
	the statement which is being resolved comes from a predefined library
	unit, all non-predefined library interpretations are skipped.
	(Resolve_Op_Concat): If string concatenation was folded in the parser,
	but the "&" is user defined, give an error, because the folding would
	be wrong.

	* sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
	the parser has folded a long sequence of concatenations of string
	literals.

	* trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
	and "JMP_BUF" variables as artificial.
	(N_String_Literal): Do not use alloca for very long string literals. Use

	    Ed Schonberg  <schonberg@adacore.com>

	* inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
	Suppress unmodified in-out parameter warning in some cases
	This patch is a also fairly significant change to the way suppressible
	checks are handled.

	* checks.ads, checks.adb (Install_Null_Excluding_Check): No check
	needed for access to concurrent record types generated by the expander.
	(Generate_Range_Check): When generating a temporary to capture the
	value of a conversion that requires a range check, set the type of the
	temporary before rewriting the node, so that the type is always
	properly placed for back-end use.
	(Apply_Float_Conversion_Check): Handle case where the conversion is
	truncating.
	(Get_Discriminal): Code reformatting. Climb the scope stack looking
	for a protected type in order to examine its discriminants.

	* a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
	a-stwisu.adb, a-strsup.adb: Fix warnings for range
	tests optimized out.

	* exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
	(Get_Allocator_Final_List): For the case of an anonymous access type
	that has a specified Associated_Final_Chain, do not go up to the
	enclosing scope.
	(Expand_N_Type_Conversion): Test for the case of renamings of access
	parameters when deciding whether to apply a run-time accessibility
	check.
	(Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
	aggregate code before allocator, and ahead of declaration for
	temporary, to prevent access before elaboration when the allocator is
	an actual for an access parameter.
	(Expand_N_Type_Conversion): On an access type conversion involving an
	access parameter, do not apply an accessibility check when the
	operand's original node was an attribute other than 'Access. We now
	create access conversions for the expansion of 'Unchecked_Access and
	'Unrestricted_Access in certain cases and clearly accessibility should
	not be checked for those.

	* exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
	includes a type conversion of a packed component that has been expanded,
	recover the original expression for the object, and use this expression
	in the post-call assignment statement, so that the assignment is made
	to the object and not to a back-end temporary.
	(Freeze_Subprogram): In case of primitives of tagged types not defined
	at the library level force generation of code to register the primitive
	in the dispatch table. In addition some code reorganization has been
	done to leave the implementation clear.
	(Expand_Call): When expanding an inherited implicit conversion,
	preserve the type of the inherited function after the intrinsic
	operation has been expanded.

	* exp_ch2.ads, exp_ch2.adb
	(Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
	of an entry formal appearing in an assignment statement does not assign
	to the formal.
	(Expand_Current_Value): Instead of calling a routine to determine
	whether the prefix of an attribute reference should be optimized or
	not, prevent the optimization of such prefixes all together.

	* lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
	component whose prefix is known to be of an access type is an implicit
	dereference and does not assign to the prefix.

2007-08-14  Ed Schonberg  <schonberg@adacore.com>
	    Robert Dewar  <dewar@adacore.com>

	* atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
	itype is visited, make an entry into table to link associated node and
	new itype.
	Add comments and correct harmless error in Build_NCT_Hash_Tables
	(Array_Aggr_Subtype): Associate each itype created for an index type to
	the corresponding range construct, and not to the aggregate itself. to
	maintain a one-to-one correspondence between itype and its associated
	node, to prevent errors when complex expression is copied.
	Fix mishandling of multiple levels of parens

	* sem_aggr.adb: Create a limited view of an incomplete type, to make
	treatment of limited views uniform for all visible declarations in a
	limited_withed package.
	(New_Copy_Tree): If hash table is being used and itype is visited,
	make an entry into table to link associated node and new itype.
	(Resolve_Record_Aggregate): Do not add an others box association for a
	discriminated record component that has only discriminants, when there
	is a box association for the component itself.

	* par-ch4.adb: Fix mishandling of multiple levels of parens

	possible trailing spaces.
	(Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
	Fix problem with suppressing warning messages from back end
	Improve handling of deleted warnings

	* gnat1drv.adb:
	Fix problem with suppressing warning messages from back end

	Improve warnings for in out parameters
	(Set_Related_Interaface/Related_Interface): Allow the use of this
	attribute with constants.
	(Write_Field26_Name): Handle attribute Related_Interface in constants.
	Warn on duplicate pragma Preelaborable_Initialialization

	* sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
	generation of a freezing node to ensure proper management of null
	excluding access types in the backend.
	(Create_Extra_Formals): Test base type of the formal when checking for
	the need to add an extra accessibility-level formal. Pass the entity E
	on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
	originally being done in a couple of cases), to ensure that the
	Extra_Formals list gets set on the entity E when the first entity is
	added.
	(Conforming_Types): Add missing calls to Base_Type to the code that
	handles anonymous access types. This is required to handle the
	general case because Process_Formals builds internal subtype entities
	to handle null-excluding access types.
	(Make_Controlling_Function_Wrappers): Create wrappers for constructor
	functions that need it, even when not marked Requires_Overriding.
	Improve warnings for in out parameters
	(Analyze_Function_Return): Warn for disallowed null return
	Warn on return from procedure with unset out parameter
	Ensure consistent use of # in error messages
	(Check_Overriding_Indicator): Add in parameter Is_Primitive.
	(Analyze_Function_Return): Move call to Apply_Constraint_Check before
	the implicit conversion of the expression done for anonymous access
	types. This is required to generate the code of the null excluding
	check (if required).

	* sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
	A formal parameter is never publicly referenceable outside of its body.
	(Check_References): For an unreferenced formal parameter in an accept
	statement, use the same warning circuitry as for subprogram formal
	parameters.
	(Warn_On_Unreferenced_Entity): New subprogram, taken from
	Output_Unreferenced_Messages, containing the part of that routine that
	is now reused for entry formals as described above.
	(Goto_Spec_Entity): New function
	(Check_References): Do not give IN OUT warning for dispatching operation
	Improve warnings for in out parameters
	(Test_Ref): Check that the entity is not undefinite before calling
	Scope_Within, in order to avoid infinite loops.
	Warn on return from procedure with unset out parameter
	Improved warnings for unused variables

	* exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
	(Expand_N_Attribute_Reference): Further unify the handling of the
	three forms of access attributes, using common code now for all three
	cases. Add a test for the case of applying an access attribute to
	an explicit dereference when the context is an access-to-interface
	type. In that case we need to apply the conversion to the prefix
	of the explicit dereference rather than the prefix of the attribute.
	(Attribute_Version, UET_Address): Set entity as internal to ensure
	proper dg output of implicit importation.
	(Expand_Access_To_Type): Removed.
	(Expand_N_Attribute_Reference): Merge the code from the three cases
	of access attributes, since the processing is largely identical for
	these cases. The substantive fix here is to process the case of a
	type name prefix (current instance case) before handling the case
	of interface prefixes.

	(Freeze_Array_Type, Freeze_Record_Type): For the case of a component
	type that is an anonymous access to controlled object, establish
	an associated finalization chain to avoid corrupting the global
	finalization list when a dynamically allocated object designated
	by such a component is deallocated.
	(Make_Controlling_Function_Wrappers): Create wrappers for constructor
	functions that need it, even when not marked Requires_Overriding.
	(Initialize_Tag): Replace call to has_discriminants by call to
	Is_Variable_Size_Record in the circuitry that handles the
	initialization of secondary tags.
	(Is_Variable_Size_Record): New implementation.
	(Expand_N_Object_Declaration): Suppress call to init proc if there is a
	Suppress_Initialization pragma for a derived type.

	(Make_Select_Specific_Data_Table): Handle private types.
	(Tagged_Kind): Handle private types.
	(Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
	output of implicit importation and exportation.

	* exp_util.ads, exp_util.adb:
	This patch replaces a number of occurrences of explicit tests for N_Null
	with calls to Known_Null. This improves tracking of null values, since
	Known_Null also catches null constants, and variables currently known to
	be null, so we get better tracking.
	(Ensure_Defined): create an itype reference only in the scope of the
	itype.
	(Side_Effect_Free): A selected component of an access type that
	denotes a component with a rep clause must be treated as not
	side-effect free, because if it is part of a linked structure its
	value may be affected by a renaming.
	(Expand_Subtype_From_Expr): For limited objects initialized with build
	in place function calls, do nothing; otherwise we prematurely introduce
	an N_Reference node in the expression initializing the object, which
	breaks the circuitry that detects and adds the additional arguments to
	the called function. Bug found working in the new patch for statically
	allocated dispatch tables.
	(Is_Library_Level_Tagged_Type): New subprogram.
	(Remove_Side_Effects): If the expression of an elementary type is an
	operator treat as a function call.

	attributes properly to compute the constraint on the resulting aggregate
	which is a string.

	* freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
	class-wide type whose base type is an incomplete private type, leave
	class-wide type unfrozen so that freeze nodes can be generated
	properly at a later point.
	(Freeze_Entity, array case): Handle case of pragma Pack and component
	size attributre clause for same array.

	Load_Parent_Of_Generic, to instantiate all bodies in the compilation
	unit being loaded, to ensure that the generation of global symbols is

	takes progenitor types into account.
	(Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by

	an access_to_constant type.
	(Try_Primitive_Operation): If the type of the prefix is a formal tagged
	type, the candidate operations are found in the scope of declaration of
	the type, because the type has no primitive subprograms.
	(Analyze_Selected_Component): If prefix is class-wide, and root type is

	Take into account the Ada2005 pragma Has_Preelaborable_Initialization
	when checking the legality of an extension aggregate in a preelaborable
	package. Treat the literal null as a valid default expression in a
	component declaration for a type with preelaborable initialization.
	A limited interface is a legal progenitor for the designated type of a
	remote access to class-wide type.

	when the type of the interpretation matches that of the context.
	(Resolve): When looping through all possible interpretations of a node,
	do not consider those that are hidden by abstract operators.
	(Resolve_Actuals): When verifying that an access to class-wide object
	is an actual  for a controlling formal, ignore anonymous access to
	subprograms whose return type is an access to class_wide type.
	(Resolve_Slice): If the prefix of the slice is a selected component
	whose type depends on discriminants, build its actual subtype before
	applying range checks on the bounds of the slice.

	Update comments.

	* sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
	class-wide types visible through limited-with clauses.
	(Try_Primitive_Operation): When examining all primitive operations of a
	tagged type, do not consider subprograms labeled as hidden unless they
	belong to a private generic type with a tagged parent.
	(Try_Object_Operation): Extensive rewriting, to handle properly various
	overloading cases, when several ancestors may have class-wide operations
	that are possible candidates, and when the overloaded functions return
	array types and have defaulted parameters so that the call may be
	interpreted as an indexing.
	(Analyze_Allocator): Remove Mark_Allocator and its invocation.
	(Process_Function_Call): use Next, rather than Next_Actual, to analyze
	successive actuals before analyzing the call itself.
	(Try_Primitive_Operation): A primitive operation is compatible with the
	prefix if the prefix has a synchronized type and the type of the formal
	is its corresponding record, as can be the case when the primitive
	operation is declared outside of the body of the type.
	(Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
	perform homonym traversal, looking for class-wide operation matches
	(formerly done in statements of Try_Class_Wide_Operation). Matches on
	access parameters are now restricted to anonymous access types.
	(Mark_Allocator): An allocator with a discriminant association parent is
	a coextension.
	(Try_One_Prefix_Interpretation): If the type of the object is
	incomplete, as can be happen when it is a limited view obtained through
	a limited_with_clause, the selected component is not part of a prefixed
	call.
	(Complete_Object_Operation): Diagnose properly an object that is not
	aliased when the corresponding controlling formal is an access
	parameter.
	(Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
	ambiguous calls in prefixed notation, where two primitives differ only
	in that the controlling argument of one is an access parameter.

	* sem_ch6.adb (Has_Single_Return): Add guard in code that determines
	whether a function that returns an unconstrained type can be inlined.
	(Process_Formals): Diagnose properly the illegal use of an incomplete
	type in the profile of an access_to_subprogram declaration.
	(Check_Synchronized_Overriding): Nothing check for concurrent types, the
	operations are attached to the corresponding record.
	(Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
	When processing a primitive of a concurrent type which implements an
	interface change the type of all controlling formals to that of the
	corresponding record type.
	(Check_Synchronized_Overriding): Relax the conditional logic when trying
	to determine the tagged type to which a primitive belongs.
	(Check_Conventions): Capture condition to ignore a primitive operation
	(which is shared between the loop in Check_Conventions and the one in
	Check_Convention) in a new local function Skip_Check.
	(Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
	confusion with Check_Conventions' own Prim_Op local variable.
	(Create_Extra_Formals): Test for a tagged result type rather than a
	controlling result when determining whether to add a BIP_Alloc_Form
	formal and a BIP_Final_List formal to the function.
	(Check_Conformance); For parameters that are anonymous access types,
	subtype conformance requires that the not null and the constant
	indicators must match
	(Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
	to retrieve the appropriate type when processing a concurrent type
	declared within a generic. Minor comment reformatting. Change invocation
	of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
	mitive.
	(Analyze_Subprogram_Body): If the return type of a function is an
	anonymous access to the limited view of a class-wide type, and the
	non-limited view of the type is available, update the type of the
	function so that code can be generated.
	(Process_Formals): In case of access-subtype itype whose designated
	type is also an itype (situation that happens now with access to
	subprograms) we mark the access-type itype with the Has_Delayed_Freeze
	attribute to avoid backend problems.
	(Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
	init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
	anonymous types' designated types are same before testing
	Subtypes_Statically_Match.
	(Create_Extra_Formals): Test for a named access parameter that is a
	controlling formal as an additional condition for adding an
	accessibility level formal. This can occur in the subp type created for
	dispatching calls in Expand_Dispatching_Call, and allows calling
	Create_Extra_Formals from that procedure rather than special-casing the
	extra formals there.
	(Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
	when the function has a controlling result.
	(Check_Returns): Add much more knowledge of the optimization of local
	raise statements to gotos, to retain proper warnings in this case.
	(Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
	nodes when looking for last statement.

	* sem_type.ads, sem_type.adb (Specific_Type): Add support for
	class-wide types visible through limited with clauses.
	(Add_One_Interp): If the operands are anonymous access types, the
	predefined operator on universal_access is immediately visibles
	(Find_Unique_Type): Handle anonymous access to subprogram types just as
	other anonymous access types.
	(Disambiguate): Take into account CIL convention.
	(Interface_Present_In_Ancestor): Add support for class-wide interfaces.

	sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
	elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
	Fix lower bound of tables.
	Add rep clauses.

	* nlists.adb: Ditto.
	(Prev_Node, Next_Node): Change index type to Int so that it properly
	covers the range First_Node_Id - 1 up.

	* exp_aggr.ads, exp_aggr.adb:
	(Build_Record_Aggr_Code): Add missing initialization of secondary tags
	in extension aggregates.
	(Flatten): Other conditions being met, an aggregate is static if the
	low bound given by component associations is different from the low
	bound of the base index type.
	(Packed_Array_Aggregate_Handled): If the component type is itself a
	packed array or record, the front-end must expand into assignments.
	(Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
	Init_Pr, instead of Ancestor_Is_Expression.
	(Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
	coextension chain root, either generate a list controller or use the
	already existing one.
	(Static_Array_Aggregate): New procedure to construct a positional
	aggregate that can be handled by the backend, when all bounds and
	components are compile-time known constants.
	(Expand_Record_Aggregate): Force conversion of aggregates of tagged
	types covering interface types into assignments.
	(Replace_Type): move to Build_Record_Aggr_Code.
	(Expand_Record_Aggr_Code): if the target of the aggregate is an
	interface type, convert to the definite type of the aggregate itself,
	so that needed components are visible.
	(Convert_Aggr_In_Object_Decl): If the aggregate has controlled
	components and the context is an extended return statement do not
	create a transient block for it, to prevent premature finalization
	before the return is executed.
	(Gen_Assign): Do not generate a call to deep adjust routine if the
	component type is itself an array of controlled (sub)-components
	initialized with an inner aggregate.
	(Component_Check): New name for Static_Check. This name is now more
	appropriate, and documentation is added which was missing.
	(Component_Check): Add test for bit aligned component value
	(Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
	Tagged_Comps, name is more appropriate given added function below.
	(Component_Not_OK_For_Backend): Check for bit aligned component ref.

	* exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
	Terminated: Add unchecked type conversion from System.Address to
	System.Tasking.Task_Id when calling the predefined primitive
	_disp_get_task_id.
	Disable new Ada 05 accessibility check for JVM.NET targets, which
	cannot be implemented in a practical way.
	(Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
	the sources always references the tag of the actual object. Therefore,
	if 'Tag is applied in the sources to class-wide interface objects we
	generate code that displaces "this" to reference the base of the object.
	(Expand_N_Attribute_Reference, case Size): Return specified size if
	known to front end.
	(Expand_N_Attribute_Reference): The expansion of the 'Address attribute
	has code that displaces the pointer of the object to manage interface
	types. However this code must not be executed when the prefix is a
	subprogram. This bug caused the wrong expansion of the internally
	generated assignment that fills the dispatch table when the primitive
	is a function returning a class-wide interface type.
	(Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
	Set_Attribute_Name for Name_Unaligned_Valid.

	    Gary Dismukes  <dismukes@adacore.com>

	* exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
	If the initialization is the equivalent aggregate of the initialization

	(Expand_N_Attribute_Definition_Clause): Exclude access variables
	initialized to null from having their expression reset to empty and
	note this exception in the comment.

	* exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
	Add "with" and "use" clauses for Sem_Attr.
	(Expand_Current_Value): Do not replace occurences of attribute
	references where the prefix must be a simple name.

	* sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
	Namet. Add new arrays Attribute_Name_Modifies_Prefix and
	Attribute_Requires_Simple_Name_Prefix.
	(Name_Modifies_Prefix): Body of new function.
	(Requires_Simple_Name_Prefix): Body of new function.
	(Resolve_Attribute, case Access): Improve error message for case of
	mismatched conventions.
	(Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
	incomplete type.
	(Analyze_Attribute, case 'Access): If the type of the prefix is a
	constrained subtype for a nominal unconstrained type, use its base type
	to check for conformance with the context.
	(Resolve_Attribute): Remove test of the access type being associated
	with a return statement from condition for performing accessibility
	checks on access attributes, since this case is now captured by
	Is_Local_Anonymous_Access.
	(Analyze_Access_Attribute): Set Address_Taken on entity
	(Analyze_Attribute, case Address): Set Address_Taken on entity
	(OK_Self_Reference): Traverse tree to locate enclosing aggregate when
	validating an access attribute whose prefix is a current instance.
	(Resolve_Attribute): In case of attributes 'Code_Address and 'Address
	applied to dispatching operations, if freezing is required then we set
	the attribute Has_Delayed_Freeze in the prefix's entity.
	(Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
	current scope if access of local subprogram taken
	(Analyze_Access_Attribute): Check legality of self-reference even if the
	expression comes from source, as when a single component association in
	an aggregate has a box association.
	(Resolve_Attribute, case 'Access): Do not apply accessibility checks to
	the prefix if it is a protected operation and the attribute is
	Unrestricted_Access.
	(Resolve_Attribute, case 'Access): Set the Etype of the attribute
	reference to the base type of the context, to force a constraint check
	when the context is an access subtype with an explicit constraint.
	(Analyze_Attribute, case 'Class): If the prefix is an interface and the
	node is rewritten as an interface conversion. leave unanalyzed after
	resolution, to ensure that type checking against the context will take
	place.

	* exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
	wrapper when the full view of the controlling type of an inherited
	function that dispatches on result implements interfaces.
	(Expand_N_Object_Declaration): In cases where the type of the
	declaration is anonymous access, create finalization list for it.
	(Expand_N_Object_Declaration): Generate a persistent_bss directive only
	if the object has no explicit initialization, to match description of
	functionality of pragam Persistent_BSS.
	(Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
	new function to build static aggregates, to replace initialization call
	when static initialization is desired.
	(Freeze_Type): Generate a list controller for an access type whenever
	its designated type has controlled anonymous access discriminants.
	(Build_Equivalent_Aggregate): New procedure to compute a static
	aggregate to be used as default initialization for composite types,
	instead of a generating a call to the initialization procedure for the
	type.
	(Build_Initialization_Call): When available, replace a call to the
	initialization procedure with a copy of the equivalent static aggregate
	for the type.
	(Expand_N_Object_Declaration):  Use New_Occurrence_Of in generated
	declarations for objects of a class-wide interface type, rather than
	just identifiers, to prevent visibility problems.
	(Expand_N_Object_Declaration): When expanding the declaration for an
	object of a class-wide interface type, preserve the homonym chain of
	the original entity before exchanging it with that of the generated
	renaming declaration.
	(Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
	active, because there is no way to handle the exception.
	(Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
	to do a minimum decoration of the Access_Disp_Table list.
	(Expand_Record_Controller): Avoid the addition of the controller between
	the component containing the tag of a secondary dispatch table and its
	adjacent component that stores the offset to the base of the object.
	This latter component is only generated when the parent type has
	discriminants ---documented in Add_Interface_Tag_Components).
	(Apply_Array_Size_Check): Removed, no longer needed.
	(Expand_N_Full_Type_Declaration): If the type has anonymous access
	components, create a Master_Entity for it only if it contains tasks.
	(Build_Init_Procedure): Suppress the tag assignment compiling under
	no run-time mode.
	(Freeze_Record_Type): Remove code associated with creation of dispatch
	table.
	(Init_Secondary_Tags): Update type of actuals when generating calls to
	Ada.Tags.Set_Offset_To_Top
	(Stream_Operation_OK): Disable use of streams compiling under no
	run-time mode
	(Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
	if Has_Init_Expression set.
	(Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
	Register_Primitive, which provides the same functionality.
	(Requires_Init_Proc): Return false in case of interface types.
	(Add_Secondary_Tables): Use the new attribute Related_Interface to
	cleanup the code.
	(Predefined_Primitive_Freeze): Do not assume that an internal entity
	is always associated with a predefined primitive because the internal
	entities associated with interface types are not predefined primitives.
	Therefore, the call to Is_Internal is replaced by a call to the
	function Is_Predefined_Dispatching_Operation.
	(Make_Eq_If): When generating the list of comparisons for the
	components of a given variant, omit the controller component that is
	present if the variant has controlled components.

	    Hristian Kirtchev  <kirtchev@adacore.com>
	    Bob Duff  <duff@adacore.com>

	* exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
	handle the creation of finalization lists and calls for nested
	coextensions when the root of the chains is part of a return statement.
	(Inside_A_Return_Statement): New function inside Complete_Coextension_
	Finalization.
	(Expand_Record_Equality): Skip components that are interface types.
	(Displace_Allocator_Pointer): Add missing support for interface subtypes
	(Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
	with Rewrite_Coextension. Change the condition for detecting coextension
	root nodes.
	(Is_Local_Access_Discriminant): Removed.
	(Rewrite_Coextension): New routine which rewrites a static coextension
	as a temporary and uses its unrestricted access in the construction of
	the outer object.
	(Complete_Coextension_Finalization): New routine. Generate finalization
	attachment calls to all delayed coextensions.
	(Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
	the allocator is not a coextension itself and has delayed coextensions.
	If the current allocator is controlled, but also a coextension, delay
	the generation of the finalization attachment call.
	Rename local variable "Node" to "Nod" in order to avoid confusion with
	"Elists.Node".
	(Expand_Allocator_Expression): Call Adjust for initialized allocators of
	limited types that are not inherently limited. Such an allocator is
	illegal, but is generated by the expander for a return statement, to
	copy the result onto the secondary stack. This is the only case where a
	limited object can be copied. Generate code to displace the pointer
	to the object if the qualified expression is a class-wide interface
	object. Such displacement was missing and hence the copy of the object
	was wrong.
	(Apply_Accessibility_Check): Handle allocated objects initialized in
	place.
	(Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
	and Expand_Allocator_Expression. Allocating class-wide interface objects
	this routine displaces the pointer to the allocated object to reference
	the component referencing the corresponding secondary dispatch table.
	Expand_Allocator_Expression): Add missing support to allocate class-wide
	interface objects initialized with a qualified expression.
	(Get_Allocator_Final_List): Test for an anonymous access type that is a
	function result type, and use the finalization list associated with the
	function scope in that case (such an anonymous type should not be
	treated like an access parameter's type).

	* exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
	controlled type, use Make_Handler_For_Ctrl_Operation to construct the
	required exception handler.
	(Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
	properly the case of a function whose return type is a limited
	class-wide interface type. Modify the code of the accessibility
	check to handle class-wide interface objects. In this case we need to
	displace "this" to reference the primary dispatch table to get access
	to the TSD of the object (to evaluate its accessibility level).
	(Expand_N_Extended_Return_Statement): Test for a tagged result type
	rather than a controlling result as one of the conditions for
	generating tests of the implicit BIP_Alloc_Form formal. The
	initialization assignment is also handled according to whether the
	result is tagged instead of controlling.
	In the case where the init assignment is inserted in the "then" part of
	the allocation conditional, rewrite the target to be a dereference of
	the implicit BIP_Object_Access formal.
	If the returned value is unconstrained and created on the secondary
	stack, mark the enclosing block and function so that the secondary
	stack is not reclaimed on return.
	Treat returns from functions with controlling results similarly to
	returns from functions with unconstrained result subtypes.
	If the object returned is unconstrained, and an allocator must be
	created for it, analyze the allocator once the block for the extended
	return is installed, to ensure that finalizable components
	of the expression use the proper finalization list. Guard the call to
	Move_Final_List with a check that there is something to finalize.
	(Make_Tag_Ctrl_Assignment): Use "old" handling
	of controlled type assignment for virtual machines, since new code uses
	unsupported features (such as direct access to bytes in memory).

2007-06-06  Gary Dismukes  <dismukes@adacore.com>
	    Ed Schonberg  <schonberg@adacore.com>

	* exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
	accessibility actual, check for the case of an aliased object that has
	been rewritten as an Access attribute, and assign Prev to Prev_Orig so
	we fall into processing for the attribute rather than the name of the
	object.
	(Expand_Inline_Call): If an actual is a literal, and the corresponding
	formal has its address taken in the body, create a temporary to capture
	value.  If the return type is a limited interface, do not treat the
	return value as Controlled.
	(Is_In_Place_Function):  If the return type is a limited interface,
	treat as returning in place. The actual returned object may not always
	be limited, but the caller has to assume that it is returned in place.
	(Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
	context of an allocator, use the correct finalization chain (that is,
	the chain belonging to the access type, rather than the chain belonging
	to the current scope).
	(Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
	result type rather than a controlling result as a precondition for
	adding an allocation form actual to a build-in-place call.
	(Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
	(Freeze_Subprogram): Code cleanup. Remove all the code that register the
	primitive in the dispatch tables. This work is now done by Make_DT when
	the type is frozen.
	(Register_Predefined_DT_Entry): Removed.
	(Add_Return): If end label is not present, use sloc of last statement
	for generated return statement in procedure, for better gdb behavior
	on expanded code.
	(Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
	object address nodes to ensure proper processing by routines like
	Insert_After*.
	(Expand_Call): Fix generation of validity check for parameter
	(Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
	the allocation form parameter if the result subtype is constrained,
	except when the function has a controlling result.
	(Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
	rather than Is_Controlled and Has_Controlled_Component, since we want to
	include class-wide result types in this treatment. Also test for a
	controlling result, since that also requires passing a finalization
	list.
	(Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
	even when the result subtype is constrained, to handle calls involving
	controlling results.
	(Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
	is now called even when the result subtype is constrained, to handle
	calls involving controlling results.
	(Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
	on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
	now performs the test).
	(Make_Build_In_Place_Call_In_Object_Declaration):
	Add_Alloc_Form_Actual_* is now called even when the result subtype is
	constrained, to handle calls involving controlling results.
	(Add_Return): Accomodate rewritten pattern from local raise to goto
	transformation, so that we still recognize an transfer statement
	and do the right thing here in that case.
	(Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
	and end of subprogram code.
	(Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
	support for primitives that are functions (without formals) with a
	controlling result.
	(Inherited_From_Formal): If the actual subtype has not generic parent
	type, it is not an actual for a formal derived type, and there is no
	operation to inherit from the formal.

	exception handler for Deep_Adjust or Deep_Finalize.
	(Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
	Raise_From_Controlled_Operation is available, use a call to that
	subprogram instead of a plain "raise Program_Error" node to raise
	Program_Error if an exception is propagated from an Adjust or Finalize
	operation.
	(Insert_Actions_In_Scope_Around): If the statement to be wrapped

	* exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
	functionality when the backend is generating code.
	Otherwise any serious error
	reported by the backend calling the frontend routine Error_Msg
	changes the Compilation_Mode to Check_Semantics, disables the

	Modify the declaration of the object containing the TSD
	because we now expand code that has a higher level of abstraction.
	The TSD has a discriminant containing the Inheritance Depth Level,
	value that is used in the membership test but also to fix the size
	of the table of ancestors.
	(Expand_Interface_Conversion): Insert function body at the closest place
	to the conversion expression, to prevent access-before-elaboration
	errors in the backend.
	Code improved to reduce the size of the dispatch table if

	calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
	Address.
	(Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
	the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

	First/Next_Component_Or_Discriminant
	(Insert_Actions): Add entries for new N_Push and N_Pop nodes

	provided by the function Has_Abstract_Interfaces.
	(Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
	support concurrent types implementing interfaces.
	(Find_Implemented_Interface): Removed. All the calls to this subprogram
	specify kind Any_Limited_Interface, and this functionality is already
	provided by the function Has_Abstract_Interfaces.
	(Remove_Side_Effects): replace Controlled_Type by

	type, do not create a new itype for each protected body.
	If the body of a protected operation creates
	controlled types (including allocators for class-widetypes), the

	finalization list.
	(Build_Activation_Chain_Entity): Build the chain entity for extended

	Change primitive operation name for the RACW associated with a RAS
	from Call to _Call so it cannot clash with any legal identifier.

	Is_RAS.
	(Append_RACW_Bodies): New subprogram.
	(Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
	Add_Receiving_Stubs_To_Declarations functions.
	When expanding a package body, this list correspond to the
	statements in the HSS at the end of the pacakge.
	When expanding a package spec, this list correspond to the
	spec declarations.
	(Add_Receiving_Stubs_To_Declarations): Append the function
	registering the receiving stubs at the end of the 'Stmts' list.
	(RCI_Package_Locator): Pass the new Version generic formal when
	instantiating a RCI_Locator package.
	(Build_From_Any_Function): To compute the High bound for an
	unconstrained array actual, we add the Low bound with the length.
	Thus we must convert the low bound and the length to an appropriate
	type before doing the sum.
	(Build_Subprogram_Receiving_Stubs, PolyORB):
	 * Retrieve the extra formals parameters at the
	   end of the parameter stream.
	 * Use Move_Any_Value to write back out parameters
	   after executing the request as it is more efficient
	   than Copy_Any_Value.
	 * Build the any containing Extra Formals with the
	   appropriate typecode.
	(PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
	empty Component_List.
	(Build_Actual_Object_Declaration): New subprogram. Build and insert into

	Built_TypeCode_Function): When Typ is implicit, call the correct
	function with the first not implicit parent type.
	(TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
	(FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
	typecode from the Etype. Therefore we retrieve the correct typecode
	with a call to Get_Any_Type.
	(Copy_Specification): Do controlling formal type substitution based on
	Is_Controlling_Formal flag, instead of caller-provided object type.
	(Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
	a RACW primitive operation, we might get a subprogram declaration for an
	ancestor of the RACW designated type (not for the designated type
	itself), in the case where this operation is inherited. In this case we
	have no easy means of determining the original tagged type for which
	the primitive was declared, so instead we now rely on
	Copy_Specification to use the Is_Controlling_Formal flag to determine
	which formals require type substitution.

	* sem_ch10.adb (Install_Limited_Context_Clauses.
	Expand_Limited_With_Clause): Use a new copy of selector name in the

	(Install_Limited_With_Clauses): Do not install non-limited view when it
	is still incomplete.

2007-04-06  Ed Schonberg  <schonberg@adacore.com>
	    Gary Dismukes  <dismukes@adacore.com>

	* sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
	when capturing size information, instead of base type, which for a
	formal array type will be the unconstrained type.
	(Analyze_Formal_Object_Declaration): Add check for illegal default
	expressions for a formal in object of a limited type.
	(Instantiate_Object): Ditto.
	(Check_Formal_Package_Instance): Skip entities that are formal objects,
	because they were defaulted in the formal package and no check applies
	to them.
	(Check_Formal_Package_Instance): Extend conformance check to other
	discrete types beyond Integer.
	(Process_Default): Copy directly the unmatched formal. A generic copy
	has already been performed in Analyze_Formal_Package.
	(Analyze_Associations): If a formal subprogram has no match, check for
	partial parametrization before looking for a default, to prevent
	spurious errors.
	(Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
	not set the instantiation environment before analyzing the actuals.
	Fixes regression on 8515-003 with implementation of AI-133.
	Set_Instance_Env checks whether the generic unit is a predefined
	unit, in which case the instance must be analyzed with the latest Ada
	mode. This setting must take place after analysis of the actuals,
	because the actuals must be analyzed and frozen in the Ada mode extant
	outside of the current instantiation.
	(Save_Env, Restore_Env): Preserve and restore the configuration
	parameters so that predefined units can be compiled in the proper Ada
	mode.
	(Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,

	and Is_Abstract_Type.

	    Bob Duff  <duff@adacore.com>
	    Gary Dismukes  <dismukes@adacore.com>

	* sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
	prefix type is a discriminated subtype of the type of the formal.
	(Analyze_Allocator): Collect all coextensions regardless of the context.
	Whether they can be allocated statically is determined in exp_ch4.
	(Analyze_Selected_Component): If the prefix is a limited view and the
	non-limited view is available, use the non-limited one.
	(Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
	therefore illegal), suggest a qualified expression rather than a type
	conversion, because a type conversion would be illegal in this context.
	(Anayze_Allocator): Trace recursively all nested allocators so that all
	coextensions are on the corresponding list for the root. Do no mark
	coextensions if the root allocator is within a declaration for a stack-
	allocated object, because the access discriminants will be allocated on
	the stack as well.
	(Analyze_Call): Remove restriction on calls to limited functions for the
	cases of generic actuals for formal objects, defaults for formal objects
	and defaults for record components.
	(Analyze_Allocator): Before analysis, chain coextensions on the proper
	element list. Their expansion is delayed until the enclosing allocator
	is processed and its finalization list constructed.
	(Try_Primitive_Operation): If the prefix is a concurrent type, looks
	for an operation with the given name among the primitive operations of
	the corresponding record type.
	(Analyze_Selected_Component): If the prefix is a task type that
	implements an interface, and there is no entry with the given name,
	check whether there is another primitive operation (e.g. a function)
	with that name.
	(Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
	properly the indexing of a function call written in prefix form, where
	the function returns an array type, and all parameters of the function
	except the first have defaults.
	(Analyze_Equality_Op): If this is a call to an implicit inequality, keep
	the original operands, rather than relocating them, for efficiency and
	to work properly when an operand is overloaded.
	(Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
	Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
	(Analyze_Selected_Component): If the prefix is a private extension, only
	scan the visible components, not those of the full view.
	(Try_Primitive_Operation): If the operation is a procedure, collect all
	possible interpretations, as for a function, because in the presence of
	classwide parameters several primitive operations of the type can match
	the given arguments.

2007-04-06  Ed Schonberg  <schonberg@adacore.com>
	    Robert Dewar  <dewar@adacore.com>

	    Thomas Quinot  <quinot@adacore.com>

	* sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
	out of Analyze_Package_Declaration, because processing must be applied
	to package bodies as well, for deferred constants completed by pragmas.
	(Analyze_Package_Declaration): When the package declaration being
	analyzed does not require an explicit body, call Check_Completion.
	(May_Need_Implicit_Body): An implicit body is required when a package
	spec contains the declaration of a remote access-to-classwide type.
	(Analyze_Package_Body): If the package contains RACWs, append the
	pending subprogram bodies generated by exp_dist at the end of the body.
	(New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
	Is_Abstract_Subprogram and Is_Abstract_Type.
	(Preserve_Full_Attributes): The full entity list is not an attribute
	that must be preserved from full to partial view.

	* sem_dist.adb (Add_RAS_Dereference_TSS):
	Change primitive name to _Call so it cannot clash with any legal
	identifier, and be special-cased in Check_Completion.
	Mark the full view of the designated type for the RACW associated with
	a RAS as Comes_From_Source to get proper view switching when installing
	private declarations.
	Provite a placeholder nested package body along with the nested spec
	to have a place for Append_RACW_Bodies to generate the calling stubs
	and stream attributes.

2007-04-06  Ed Schonberg  <schonberg@adacore.com>
	    Robert Dewar  <dewar@adacore.com>

	* sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
	predicate recursive, to handle complex expressions on literals whose
	spurious ambiguity comes from the abstract interpretation of some
	subexpression.
	(Interface_Present_In_Ancestor): Add support to concurrent record
	types.
	(Add_One_Interp,Disambiguate): Split Is_Abstract flag into
	Is_Abstract_Subprogram and Is_Abstract_Type.

	    Javier Miranda  <miranda@adacore.com>

	* sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
	dereference of a local object R created as a reference to another
	object O, use the access level of O.
	(Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
	rather than local Same_Formal_Type, to check whether protected operation
	overrides an inherited one.
	(Same_Formal_Type): New predicate, used when matching signatures of
	overriding synchronized operations, to handle the case when a formal
	has a type that is a generic actual.
	(Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
	predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
	(Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
	syntactic ambiguities involving indexing of function calls that return
	arrays.
	(Abstract_Interface_List): New subprogram that returns the list of
	abstract interfaces associated with a concurrent type or a
	concurrent record type.
	(Interface_Present_In_Parent): New subprogram used to check if a
	given type or some of its parents implement a given interface.
	(Collect_Abstract_Interfaces): Add support for concurrent types
	with interface types.
	(Has_Abstract_Interfaces): Add support for concurrent types with
	interface types.
	(Is_Parent): New subprogram that determines whether E1 is a parent
	of E2. For a concurrent type its parent is the first element of its
	list of interface types; for other types this function provides the
	same result than Is_Ancestor.
	(Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
	(Collect_Synchronized_Interfaces): Removed because the subprogram
	Collect_Abstract_Interfaces provides this functionality.
	(Collect_Abstract_Interfaces): Minor update to give support to
	concurrent types and thus avoid undesired code duplication.
	(Get_Subprogram_Entity): Handle entry calls.
	(May_Be_Lvalue): Include actuals that appear as in-out parameters in
	entry calls.
	(Enter_Name): Do not give -gnatwh hiding warning for record component
	entities, they never result in hiding.

	* trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
	expression with a COMPOUND_EXPR including the call instead of emitting

	high bound is constant and the slice is empty.  Tidy.
	(tree_transform, case N_Op_Not): Handle properly the case where the
	operation applies to a private type whose full view is a modular type.
	(Case_Statement_To_gnu): If an alternative is an E_Constant with an
	Address_Clause, use the associated Expression as the GNAT tree
	representing the choice value to ensure the corresponding GCC tree is
	of the proper kind.
	(maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
	instead of just the operands, as the base GCC stabilize_reference does.
	<CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
	requested; otherwise fail.

	provides both quotient and remainder in a single computation.
	(UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
	functions for uint.

	with controlled types (because the dispatch table of the ancestor is
	null and hence these entries cannot be inherited). This is required to
	elaborate well the dispatch table.

	Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
	untagged designated types).
	(Expand_N_Unchecked_Type_Conversion): Do not do integer literal
	optimization if source or target is biased.
	(Expand_N_Allocator): Add comments for case of an allocator within a
	function that returns an anonymous access type designating tasks.

	    Ed Schonberg  <schonberg@adacore.com>

	* exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.

	* exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
	(Expand_N_Assignment_Statement): Call
	Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
	build-in-place function call. Currently, this can happen only for
	assignments that come from aggregates.
	Add -gnatd.l --Use Ada 95 semantics for limited function returns,
	in order to alleviate the upward compatibility introduced by AI-318.
	(Expand_N_Extended_Return_Statement): Add support for handling the
	return object as a build-in-place result.
	(Expand_Non_Function_Return): Implement simple return statements nested
	within an extended return.
	(Enable_New_Return_Processing): Turn on the new processing of return
	statements.
	(Expand_Non_Function_Return): For a return within an extended return,
	don't raise Program_Error, because Sem_Ch6 now gives a warning.
	(Expand_N_Extended_Return_Statement): Implement AI-318
	(Expand_Simple_Function_Return): Ditto.
	(Expand_N_If_Statement): Handle new -gnatwt warning
	(Expand_N_Case_Statement): Handle new -gnatwt warning
	(Expand_N_Assignment): Handle assignment to the Priority attribute of
	a protected object.
	(Expand_N_Assignment_Statement): Implement -gnatVe/E to control
	validity checking of assignments to elementary record components.
	(Expand_N_Return_Statement): return Class Wide types on the secondary
	stack independantly of their controlled status since with HIE runtimes,
	class wide types are not potentially controlled anymore.

	* expander.adb (Expand): Add case for new N_Extended_Return_Statement
	node kind.

	* exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
	Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
	it expects a block, procedure, or task. The return statement will get
	turned into a block, and Expand_Cleanup_Actions will happen then.

	    Ed Schonberg  <schonberg@adacore.com>
	    Bob Duff  <duff@adacore.com>
	    Gary Dismukes  <dismukes@adacore.com>

	* exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
	capability.
	(Expand_Inlined_Call): Tagged types are by-reference types, and
	therefore should be replaced by a renaming declaration in the expanded
	body, as is done for limited types.
	(Expand_Call): If this is a call to a function with dispatching access
	result, propagate tag from context.
	(Freeze_Subprogram): Enable full ABI compatibility for interfacing with
	CPP by default.
	(Make_Build_In_Place_Call_In_Assignment): New procedure to do
	build-in-place when the right-hand side of an assignment is a
	build-in-place function call.
	(Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
	of the explicit dereference of the allocator to the result subtype of
	the build-in-place function. This is needed to satisfy type checking
	in cases where the caller's return object is created by an allocator for
	a class-wide access type and the type named in the allocator is a
	specific type.
	(Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
	conversion of the reference to the declared object to the result subtype
	of the build-in-place function. This is needed to satisfy type checking
	in cases where the declared object has a class-wide type. Also, in the
	class-wide case, change the type of the object entity to the specific
	result subtype of the function, to avoid passing a class-wide object
	without explicit initialization to the back end.
	(Register_Interface_DT_Entry): Moved outside the body of
	Freeze_Subprogram because this routine is now public; it is called from
	Check_Dispatching_Overriding to handle late overriding of abstract
	interface primitives.
	(Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
	adding an implicit access actual on a call to a build-in-place function.
	(Expand_Actuals): Test for an actual parameter that is a call to a
	build-in-place function and apply
	Make_Build_In_Place_Call_In_Anonymous_Context to the call.
	(Is_Build_In_Place_Function): New function to determine whether an
	entity is a function whose calls should be handled as build-in-place.
	(Is_Build_In_Place_Function_Call): New function to determine whether an
	expression is a function call that should handled as build-in-place.
	(Make_Build_In_Place_Call_In_Allocator): New procedure for handling
	calls to build-in-place functions as the initialization of an allocator.
	(Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
	handling calls to build-in-place functions in contexts that do not
	involve init of a separate object (for example, actuals of subprogram
	calls).
	(Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
	handling calls to build-in-place functions as the initialization of an
	object declaration.
	(Detect_Infinite_Recursion): Add explicit parameter Process to
	instantiation of Traverse_Body to avoid unreferenced warning.
	(Check_Overriding_Inherited_Interfaces): Removed.
	(Register_Interface_DT_Entry): Code cleanup.
	(Register_Predefined_DT_Entry): Code cleanup.
	(Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
	inlined statements if within a transient scope.
	(Expand_Inlined_Call.Process_Formals): When replacing occurrences of
	formal parameters with occurrences of actuals in inlined body, establish
	visibility on the proper view of the actual's subtype for the body's
	context.
	(Freeze_Subprogram): Do nothing if we are compiling under full ABI
	compatibility mode and we have an imported CPP subprogram because
	for now we assume that imported CPP primitives correspond with
	objects whose constructor is in the CPP side (and therefore we
	don't need to generate code to register them in the dispatch table).
	(Expand_Actuals): Introduce copy of actual, only if it might be a bit-
	aligned selected component.
	(Add_Call_By_Copy_Node): Add missing code to handle the case in which
	the actual of an in-mode parameter is a type conversion.
	(Expand_Actuals): If the call does not come from source and the actual
	is potentially misaligned, let gigi handle it rather than rejecting the
	(Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
	Class Wide types as returning by reference independantly of their
	controlled status since with HIE runtimes class wide types are not
	potentially controlled anymore.

2006-10-31  Ed Schonberg  <schonberg@adacore.com>

	* exp_ch9.adb (Update_Prival_Types): Simplify code for entity
	references that are private components of the protected object.
	(Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
	(Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
	instantiation to deal with warnings.
	(Initialize_Protection): If expression for priority is non-static, use
	System_Priority as its expected type, in case the expression has not
	been analyzed yet.

2006-10-31  Robert Dewar  <dewar@adacore.com>

	* exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
	initialization of Homonym_Len.
	(Fully_Qualify_Name): Remove kludge to eliminate anonymous block
	names from fully qualified name. Fixes problem of duplicate
	external names differing only in the presence of such a block name.

2006-10-31  Thomas Quinot  <quinot@adacore.com>
	    Pablo Oliveira  <oliveira@adacore.com>

	* exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
	subprogram Ids, even if they are not yet assigned.
	(Build_Subprogram_Id): It is now this function that will take care of
	calling Assign_Subprogram_Ids if necessary.
	(Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
	should be done only once they are assigned.
	(Build_From_Any_Function, case of tagged types): Add missing call to
	Allocate_Buffer.
	(Corresponding_Stub_Type): New subprogram. Returns the associated stub
	type for an RACW type.
	(Add_RACW_Features): When processing an RACW declaration for which the
	designated type is already frozen, enforce E.2.2(14) rules immediately.
	(GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
	special reordering of controlling formals.

	* exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
	associated stub type for an RACW type.

2006-10-31  Ed Schonberg  <schonberg@adacore.com>

	* exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
	fixed-point operations in an integer context, i.e. as operands of a
	conversion to an integer type, indicate that result must be rounded.

2006-10-31  Robert Dewar  <dewar@adacore.com>

	* exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
	cases, pass the encoding method, since it is now required by the run
	time.

	* s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
	assumption that Str'First = 1.
	(Value_Wide_Character): Takes EM (encoding method) parameter and passes
	it on to the Value_Wide_Wide_Character call.
	(Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
	properly handles a string of the form quote-encoded_wide_char-quote.

	* s-wchcnv.adb: Minor reformatting

2006-10-31  Javier Miranda  <miranda@adacore.com>

	* exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
	run-time membership test to ensure that the constructed object
	implements the target abstract interface.

2006-10-31  Robert Dewar  <dewar@adacore.com>

	* exp_prag.adb (Expand_Pragma_Common_Object): Use a single
	Machine_Attribute pragma internally to implement the user pragma.
	Add processing for pragma Interface so that it is now completely
	equivalent to pragma Import.

	* sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
	so that it can be applied to all entities, including record components
	and enumeration literals.
	(Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
	priority ranges are correct, verify compatibility against task
	dispatching and locking policies, and if everything is correct an entry
	is added to the table containing priority specific dispatching entries
	for this compilation unit.
	(Delay_Config_Pragma_Analyze): Delay processing
	Priority_Specific_Dispatching pragmas because when processing the
	pragma we need to access run-time data, such as the range of
	System.Any_Priority.
	(Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
	Allow pragma Unreferenced as a context item
	Add pragma Preelaborable_Initialization

	* exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
	Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
	Is_Inherently_Limited_Type, because return-by-reference has no meaning
	in Ada 2005.
	(Find_Node_To_Be_Wrapped): Use new method of determining the result
	type of the function containing a return statement, because the
	Return_Type field was removed. We now use the Return_Applies_To field.

	* exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
	(Build_Task_Image_Decl): If procedure is not called from an
	initialization procedure, indicate that function that builds task name
	uses the sec. stack. Otherwise the enclosing initialization procedure
	will carry the indication.
	(Insert_Actions): Remove N_Return_Object_Declaration. We now use
	N_Object_Declaration instead.
	(Kill_Dead_Code): New interface to implement -gnatwt warning for

	(Get_Current_Value_Condition): Handle left operand of AND or AND THEN
	(Get_Current_Value_Condition): If the variable reference is within an
	if-statement, does not appear in the list of then_statments, and does

	(Get_Current_Value_Condition): Enhance to allow while statements to be
	processed as well as if statements.
	(New_Class_Wide_Subtype): The entity for a class-wide subtype does not
	come from source.
	(OK_To_Do_Constant_Replacement): Allow constant replacement within body
	of loop. This is safe now that we fixed Kill_Current_Values.
	(OK_To_Do_Constant_Replacement): Check whether current scope is

	-gnatwq/Q.
	(Warn_On_Useless_Assignment): Suppress warning if enclosing inner
	exception handler.
	(Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
	use clauses, to avoid messages on packages used to qualify, and also
	to avoid messages from obsolescent units.
	(Warn_On_Useless_Assignments): Don't generate messages for imported
	and exported variables.
	(Warn_On_Useless_Assignments): New procedure
	(Output_Obsolescent_Entity_Warnings): New procedure

2006-10-31  Olivier Hainque  <hainque@adacore.com>

	* g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the

	    Robert Dewar  <dewar@adacore.com>
	    Ed Schonberg  <schonberg@adacore.com>

	* g-awk.adb (Default_Session, Current_Session): Compile this file in
	Ada 95 mode, because it violates the new rules for AI-318.

	* g-awk.ads: Use overloaded subprograms in every case where we used to
	have a default of Current_Session. This makes the code closer to be
	correct for both Ada 95 and 2005.

	* g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
	code, relying on the fact that the compiler generates a warning
	instead of an error in -gnatg mode.

	* lib-xref.ads (Xref_Entity_Letters): Add entry for new
	E_Return_Statement entity kind.
	Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.

	* par.adb (P_Interface_Type_Definition): Addition of one formal to
	report an error if the reserved word abstract has been previously found.
	(SS_End_Type): Add E_Return for new extended_return_statement syntax.

	* par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
	parenthesized range attribute usage
	(P_Expression_No_Right_Paren): Add missing comment about error recovery.

	* par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
	in the syntax for extended_return_statement. This is not in the latest
	RM, but the ARG is expected to issue an AI allowing this.
	(P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
	N_Return_Object_Declaration. We now use N_Object_Declaration instead.
	(P_Return_Object_Declaration, P_Return_Subtype_Indication,
	P_Return_Statement): Parse the new syntax for extended_return_statement.

	* par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
	Output_End_Missing): Add error-recovery code for the new
	extended_return_statement syntax; that is, the new E_Return entry on
	the scope stack.

	* s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
	limited to nonlimited, because otherwise we violate the new Ada 2005
	rules about returning limited types in function Create_AST_Handler in
	s-asthan.adb.

	* sem.adb (Analyze): Add cases for new node kinds
	N_Extended_Return_Statement and N_Return_Object_Declaration.

	* sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
	type is in the same category as type of context before applying check,
	to prevent anomalies in instantiations.
	(Resolve_Aggregate): Remove test for limited components in aggregates.
	It's unnecessary in Ada 95, because if it has limited components, then
	it must be limited. It's wrong in Ada 2005, because limited aggregates
	are now allowed.
	(Resolve_Record_Aggregate): Move check for limited types later, because
	OK_For_Limited_Init requires its argument to have been resolved.
	(Get_Value): When copying the component default expression for a
	defaulted association in an aggregate, use the sloc of the aggregate
	and not that of the original expression, to prevent spurious
	elaboration errors, when the expression includes function calls.
	(Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
	were missing. We also didn't handle qualified expressions. Now also
	allow function calls. Use new common routine OK_For_Limited_Init.
	(Resolve_Extension_Aggregate): Minor fix to bad error message (started
	with space can upper case letter).

	* sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
	Has_Static_Discriminants flag
	(Record_Type_Declaration): Diagnose an attempt to declare an interface
	type with discriminants.
	(Process_Range_Expr_In_Decl): Do validity checks on range
	(Build_Discriminant_Constraints): Use updated form of
	Denotes_Discriminant.
	(Process_Subtype): If the subtype is a private subtype whose full view
	is a concurrent subtype, introduce an itype reference to prevent scope
	anomalies in gigi.
	(Build_Derived_Record_Type, Collect_Interface_Primitives,
	Record_Type_Declaration):  The functionality of the subprograms
	Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
	is now performed by a single routine.
	(Build_Derived_Record_Type): If the type definition includes an explicit
	indication of limitedness, then the type must be marked as limited here
	to ensure that any access discriminants will not be treated as having
	a local anonymous access type.
	(Check_Abstract_Overriding): Issue a detailed error message when an
	abstract subprogram was not overridden due to incorrect mode of its
	first parameter.
	(Analyze_Private_Extension_Declaration): Add support for the analysis of
	synchronized private extension declarations. Verify that the ancestor is
	a limited or synchronized interface or in the generic case, the ancestor
	is a tagged limited type or synchronized interface and all progenitors
	are either limited or synchronized interfaces.
	Derived_Type_Declaration): Check for presence of private extension when
	dealing with synchronized formal derived types.
	Process_Full_View): Enchance the check done on the usage of "limited" by
	testing whether the private view is synchronized.
	Verify that a synchronized private view is completed by a protected or
	task type.
	(OK_For_Limited_Init_In_05): New function.
	(Analyze_Object_Declaration): Move check for limited types later,
	because OK_For_Limited_Init requires its argument to have been resolved.
	Add -gnatd.l --Use Ada 95 semantics for limited function returns,
	in order to alleviate the upward compatibility introduced by AI-318.
	(Constrain_Corresponding_Record): If the constraint is for a component
	subtype, mark the itype as frozen, to avoid out-of-scope references to
	discriminants in the back-end.
	(Collect_Implemented_Interfaces): Protect the recursive algorithm of
	this subprogram against wrong sources.
	(Get_Discr_Value, Is_Discriminant): Handle properly references to a
	discriminant of limited type completed with a protected type, when the
	discriminant is used to constrain a private component of the type, and
	expansion is disabled.
	(Find_Type_Of_Object): Do not treat a return subtype that is an
	anonymous subtype as a local_anonymous_type, because its accessibility
	level is the return type of the enclosing function.
	(Check_Initialization): In -gnatg mode, turn the error "cannot
	initialize entities of limited type" into a warning.
	(OK_For_Limited_Init): Return true for generated nodes, since it
	sometimes violates the legality rules.
	(Make_Incomplete_Declaration): If the type for which an incomplete
	declaration is created happens to be the currently visible entity,
	preserve the homonym chain when removing it from visibility.
	(Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
	inherited subprograms.
	(Access_Definition): If this is an access to function that is the return
	type of an access_to_function definition, context is a type declaration
	and the scope of the anonymous type is the current one.
	(Analyze_Subtype_Declaration): Add the defining identifier of a regular
	incomplete subtype to the set of private dependents of the original
	incomplete type.
	(Constrain_Discriminated_Type): Emit an error message whenever an
	incomplete subtype is being constrained.
	(Process_Incomplete_Dependents): Transform an incomplete subtype into a
	corresponding subtype of the full view of the original incomplete type.
	(Check_Incomplete): Properly detect invalid usage of incomplete types
	and subtypes.

	* gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
	call it with -static-libgcc, as there are some platforms, such as
	Darwin, where one of these two switches is compulsory to link.

2006-10-31  Vincent Celier  <celier@adacore.com>

	* gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
	instead of ADA_PROJECT_PATH, for the project path.
	(Gnatls): When displaying the project path directories, use host dir
	specs.

	* prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
	names in the project path, as absolute paths may correspond to
	multi-valued VMS logical names.

2006-10-31  Vincent Celier  <celier@adacore.com>

2006-10-31  Robert Dewar  <dewar@adacore.com>

	* layout.adb (Layout_Record_Type): Deal with non-static subtypes of
	variant records
	(Layout_Variant_Record): Retrieve the discriminants from the entity
	rather than from the type definition, because in the case of a full
	type for a private type we need to take the discriminants from the
	partial view.
	(Layout_Component_List): When applying the Max operator to variants with
	a nonstatic size, check whether either operand is static and scale that
	operand from bits to storage units before applying Max.
	(Layout_Type): In VMS, if a C-convention access type has no explicit
	size clause (and does not inherit one in the case of a derived type),
	then the size is reset to 32 from 64.

	(Initialize): Remove, no longer used
	(Ar): If Ar_Exec is null, get the location of the archive builder and,
	if there is one, the archive indexer. Fail if the archive builder cannot
	be found.

	Process_Body_Clauses): If the context of a body includes a use clause
	for P.Q then a with_clause for P in the same body is not redundant,
	even if the spec also has a with_clause on P.
	Add missing continuation mark to error msg
	(Build_Limited_Views): A limited view of a type is tagged if its
	declaration includes a record extension.
	(Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
	node, even if the subunit has errors. This avoids malfunction by
	Lib.Check_Same_Extended_Unit in the presence of syntax errors.
	(Analyze_Compilation_Unit): Add circuit to make sure we get proper
	generation of obsolescent messages for with statements (cannot do
	this too early, or we cannot implement avoiding the messages in the
	case of obsolescent units withing obsolescent units).
	(Install_Siblings): If the with_clause is on a remote descendant of
	an ancestor of the current compilation unit, find whether there is
	a sibling child unit that is immediately visible.
	(Remove_Private_With_Clauses): New procedure, invoked after completing
	the analysis of the private part of a nested package, to remove from
	visibility the private with_clauses of the enclosing package
	declaration.
	(Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
	now centralized in Generate_Reference.
	(Install_Limited_Context_Clauses): Remove superfluous error
	message associated with unlimited view visible through use
	and renamings. In addition, at the point in which the error
	is reported, we add the backslash to the text of the error
	to ensure that it is reported as a single error message.
	Use new // insertion for some continuation messages
	(Expand_Limited_With_Clause): Use copy of name rather than name itself,
	to create implicit with_clause for parent unit mentioned in original
	limited_with_clause.
	(Install_Limited_With_Unit): Set entity of parent identifiers if the
	unit is a child unit. For ASIS queries.
	(Analyze_Subunit): If the subunit appears within a child unit, make all
	ancestor child units directly visible again.

	Packages_To_Check.

2006-10-31  Vincent Celier  <celier@adacore.com>

	* prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
	on VMS, change "__" to '.' before checking the name.
	(Record_Ada_Source): Always add the source file name in the list of
	of sources, even if it is not the first time, as it is for another
	source index.
	(Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
	dot, instead of replacing only the first '_'.

	* prj-part.adb (Parse): Convert project file path to canonical form

	* prj-proc.adb (Recursive_Process): Make sure that, when a project is
	extended, the project id of the project extending it is recorded in its
	data, even when it has already been processed as an imported project.

2006-10-31  Robert Dewar  <dewar@adacore.com>

	* repinfo.adb (List_Entities): Don't list entities from renaming
	declarations.

2006-10-31  Arnaud Charlet  <charlet@adacore.com>
	    Robert Dewar  <dewar@adacore.com>

	* restrict.ads, restrict.adb (Restriction_Active): Now returns False if
	only a restriction warning is active for the given restriction. This is
	desirable because we do not want to modify code in the case where only
	a warning is set.
	(Set_Profile_Restrictions): Make sure that a Profile_Warnings never
	causes overriding of real restrictions.
	Take advantage of new No_Restrictions constant.

	* raise.h: (__gnat_set_globals): Change profile.

2006-10-31  Arnaud Charlet  <charlet@adacore.com>

	* sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
	properly an attempt to apply Unchecked_Access to a protected operation.
	(OK_Self_Reference): New subprogram to check the legality of an access
	attribute whose prefix is the type of an enclosing aggregate.
	Generalizes previous mechanism to handle attribute references nested
	arbitrarily deep within the aggregate.
	(Analyze_Access_Attribute): An access attribute whose prefix is a type
	can appear in an aggregate if this is a default-initialized aggregate
	for a self-referential type.
	(Resolve_Attribute, case Access): Ditto.
	Add support for new implementation defined attribute Stub_Type.
	(Eval_Attribute, case Attribute_Stub_Type): New case.
	(Analyze_Attribute, case Attribute_Stub_Type): New case.
	(Stream_Attribute_Available): Implement using new subprogram from
	sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
	Has_Specified_Stream_Attribute flag.
	Disallow Storage_Size and Storage_Pool for access to subprogram
	(Resolve_Attribute, case 'Access et al): Take into account anonymous
	access types of return subtypes in extended return statements. Remove
	accessibility checks on anonymous access types when Unchecked_Access is
	used.
	(Analyze_Attribute): Add support for the use of 'Class to convert
	a class-wide interface to a tagged type.
	Add support for the attribute Priority.
	(Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
	whether the designated type is discriminated with a constrained partial
	view and require static matching in that case.
	Add local variable Des_Btyp. The Designated_Type
	of an access to incomplete subtype is either its non-limited view if
	coming from a limited with or its etype if regular incomplete subtype.

	* sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
	Fix predicate to identify and allow cases of (expander-generated)
	references to tag of designated object of a RACW.
	(Validate_Static_Object_Name): In Ada 2005, a formal object is
	non-static, and therefore cannot appear as a primary in a preelaborable
	package.
	(Has_Stream_Attribute_Definition): New subprogram, abstracted from
	Has_Read_Write_Attributes.
	(Has_Read_Write_Attributes): Reimplement in termes of
	Has_Stream_Attribute_Definition.
	(Missing_Read_Write_Attributes): When checking component types in a
	record, unconditionally call Missing_Read_Write_Attributes recursively
	(remove guard checking for Is_Record_Type / Is_Access_Type).

2006-10-31  Robert Dewar  <dewar@adacore.com>

	* sem_ch11.adb (Analyze_Handled_Statements): Move final test for
	useless assignments here and conditionalize it on absence of exception
	handlers.
	(Analyze_Exception_Handlers): Small code reorganization of error
	detection code, for new handling of formal packages.

2006-10-31  Ed Schonberg  <schonberg@adacore.com>
	    Hristian Kirtchev  <kirtchev@adacore.com>

	* sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
	that has been constant-folded, preserve information of original tree,
	for ASIS uses.
	(Analyze_Formal_Derived_Type): Set the limited present flag of the newly
	generated private extension declaration if the formal derived type is
	synchronized. Carry synchronized present over to the generated private
	extension.
	(Validate_Derived_Type_Instance): Ensure that the actual of a
	synchronized formal derived type is a synchronized tagged type.
	(Instantiate_Formal_Package): When creating the instantiation used to
	validate the actual package of a formal declared without a box, check
	whether the formal itself depends on a prior actual.
	(Instantiate_Formal_Subprogram): Create new entities for the defining
	identifiers of the formals in the renaming declaration, for ASIS use.
	(Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
	a renaming declaration or a subtype declaration for an actual in an
	instance, capture location information of declaration in generic, for
	ASIS use.
	(Instantiate_Formal_Package): Add comments on needed additional tests.
	AI-317 (partial parametrization) is fully implemented.
	(Validate_Private_Type_Instance): Add check for actual which
	must have preelaborable initialization
	Use new // insertion for some continuation messages
	(Analyze_Formal_Object_Declaration): Change usage of Expression to
	Default_Expression. Add type retrieval when the declaration has an
	access definition. Update premature usage of incomplete type check.
	(Check_Access_Definition): New subsidiary routine. Check whether the
	current compilation version is Ada 05 and the supplied node has an
	access definition.
	(Instantiate object): Alphabetize local variables. Handle the creation
	of new renaming declarations with respect to the kind of definition
	used - either an access definition or a subtype mark. Guard against
	unnecessary error message in the context of anonymous access types after
	they have been resolved. Add check for required null exclusion in a
	formal object declaration.
	(Switch_View): A private subtype of a non-private type needs to be
	switched (the base type can have been switched without its private
	dependents because of the last branch of Check_Private_View.
	(Check_Private_View): Do not recompute Base_Type (T), instead use cached
	value from BT.
	(Instantiate_Type): Emit an error message whenever a class-wide type of
	a tagged incomplete type is used as a generic actual.
	(Find_Actual_Type): Extend routine to handle a component type in a child
	unit that is imported from a formal package in a parent.
	(Validate_Derived_Type_Instance): Check that analyzed formal and actual
	agree on constrainedness, rather than checking against ultimate ancestor
	(Instantiate_Subprogram_Body): Create a cross-reference link to the
	generic body, for navigation purposes.

2006-10-31  Robert Dewar  <dewar@adacore.com>
	    Thomas Quinot  <quinot@adacore.com>

	* sem_ch13.adb: Storage pool cannot be given for access to subprogram
	type.
	(New_Stream_Subprogram): When processing an attribute definition clause
	for a stream-oriented subprogram, record an entity node occurring at
	the point of clause to use for checking the visibility of the clause,
	as defined by 8.3(23) as amended by AI-195.
	(New_Stream_Subprogram): New procedure, factoring behaviour from both
	 New_Stream_Function and New_Stream_Procedure.
	(New_Stream_Function, New_Stream_Procedure): Removed.
	(Analyze_Attribute_Definition_Clause, case Address): Check new
	Alignment_Check check

	* sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
	generate the same errors compiling under -gnatc.
	(Try_Object_Operation): If no candidate interpretation succeeds, but
	there is at least one primitive operation with the right name, report
	error in call rather than on a malformed selected component.
	(Analyze_Selected_Component): If the prefix is an incomplete type from
	a limited view, and the full view is available, use the full view to
	determine whether this is a prefixed call to a primitive operation.
	(Operator_Check): Verify that a candidate interpretation is a binary
	operation before checking the type of its second formal.
	(Analyze_Call): Add additional warnings for function call contexts not
	yet supported.
	(Analyze_Allocator): Move the check for "initialization not allowed for
	limited types" after analyzing the expression. This is necessary,
	because OK_For_Limited_Init looks at the structure of the expression.
	Before analysis, we don't necessarily know what sort of expression it
	is. For example, we don't know whether F(X) is a function call or an
	indexed component; the former is legal in Ada 2005; the latter is not.
	(Analyze_Allocator): Correct code for AI-287 -- extension aggregates
	were missing. We also didn't handle qualified expressions. Now also
	allow function calls. Use new common routine OK_For_Limited_Init.
	(Analyze_Type_Conversion): Do not perform some legality checks in an
	instance, because the error message will be redundant or spurious.
	(Analyze_Overloaded_Selected_Component): Do not do style check when
	setting an entity, since we do not know it is the right entity yet.
	(Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
	(Analyze_Overloaded_Selected_Component): Same change
	(Analyze_Selected_Component): Remove unnecessary prefix type retrieval
	since regular incomplete subtypes are transformed into corresponding
	subtypes of their full views.
	(Complete_Object_Operation): Treat name of transformed subprogram call
	as coming from source, for browsing purposes.
	(Try_Primitive_Operation): If formal is an access parameter, compare
	with base type of object to determine whether it is a primitive
	operation.
	(Operator_Check): If no interpretation of the operator matches, check
	whether a use clause on any candidate might make the operation legal.
	(Try_Class_Wide_Operation): Check whether the first parameter is an
	access type whose designated type is class-wide.

	* sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
	warn on infinite loops.
	Add \\ to some continuation messages
	(Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
	(Process_Bounds): If the bounds are integer literals that result from
	constant-folding, and they carry a user-defined type, preserve that type
	rather than treating this as an integer range.
	(Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
	(Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
	(Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
	left hand side of assignment.
	(Analyze_Assignment): Add suport to manage assigments to the attribute
	priority of a protected object.
	(Check_Possible_Current_Value_Condition): Allow fully qualified names
	not just identifiers.
	(Check_Possible_Current_Value_Condition): Acquire left operand of AND
	or AND THEN for possible tracking.
	(Analyze_Iteration_Scheme): Check for setting Current_Value for the
	case of while loops so we can track values in the loop body.

	* sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
	procedure cannot be a protected operation (it is a basic_declaration,
	not a subprogram_declaration).
	(Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
	Subp. Add logic for entry processing.
	(Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
	Determine whether an entry or subprogram of a protected or task type
	override an inherited primitive of an implemented interface.
	(New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
	Update the actual used in calls to Check_Overriding_Indicator.
	(Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
	generate the proper reference to the parent unit, for cross-reference.
	(Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
	Is_Formal.
	Add -gnatd.l --Use Ada 95 semantics for limited function returns,
	(Add_Extra_Formal): Revise procedure to allow passing in associated
	entity, scope, and name suffix, and handle setting of the new
	Extra_Formals field.
	(Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
	pass new parameters. Add support for adding the new extra access formal
	for functions whose calls are treated as build-in-place.
	(Analyze_A_Return_Statement): Correct casing in error message.
	Move Pop_Scope to after Analyze_Function_Return, because an extended
	return statement really is a full-fledged scope. Otherwise, visibility
	doesn't work right. Correct use of "\" for continuation messages.
	(Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
	evilly trying to call Analyze_Object_Declaration directly. Otherwise,
	the node doesn't get properly marked as analyzed.
	(Analyze_Subprogram_Body): If subprogram is a function that returns
	an anonymous access type that denotes a task, build a Master Entity
	for it.
	(Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
	proper usage of null exclusion in a result definition.
	(Process_Formals): Code cleanup and new error message.
	(Process_Formals): Detect incorrect application of null exclusion to
	non-access types.
	(Conforming_Types): Handle conformance between [sub]types and itypes
	 generated for entities that have null exclusions applied to them.
	(Maybe_Primitive_Operation): Add an additional type retrieval when the
	 base type is an access subtype. This case arrises with null exclusions.
	(New_Overloaded_Entity): Do not remove the overriden entity from the
	homonym chain if it corresponds with an abstract interface primitive.
	(Process_Formals): Replace membership test agains Incomplete_Kind with a
	call to the synthesized predicate Is_Incomplete_Type.
	(Analyze_Subprogram_Body): Check wrong placement of abstract interface
	primitives.
	(Analyze_Subprogram_Declaration): Check that abstract interface
	primitives are abstract or null.
	(Analyze_Subprogram_Specification): Remove previous check for abstract
	interfaces because it was not complete.
	(Has_Interface_Formals): Removed.

	may have only a limited view.
	(Analyze_Package_Specification): For the private part of a nested
	package, install private_with_clauses of enclosing compilation unit if
	we are in its visible part.
	(Declare_Inherited_Private_Subprograms): Complete barrier
	to ensure that the primitive operation has an alias to some parent
	primitive. This is now required because, after the changes done for the
	implementation of abstract interfaces, the contents of the list of
	primitives has entities whose alias attribute references entities of
	such list of primitives.
	(Analyze_Package_Specification): Simplify code that handles parent units
	of instances and formal packages.
	(Uninstall_Declarations): Check the convention consistency among
	primitive overriding operations of a tagged record type.

	(Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
	(Analyze_Generic_Renaming): Same fix
	(Use_One_Package): Do not take into account the internal entities of
	abstract interfaces during the analysis of entities that are marked

	(Find_Type): Handle the case of an attribute reference for
	implementation defined attribute Stub_Type (simply let the analysis of

	(Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
	type that appears in a Use_Type clause.
	(Analyze_Object_Renaming): Add support for renaming of the Priority

	 in a formal object declaration or in a subtype declaration.
	(Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.

	(In_Generic_Scope): New local routine to Analyze_Object_Renaming.
	Determine whether an entity is inside a generic scope.
	(In_Open_Scope): First pass of documentation update.

	functionality of Set_Prim_Op_Address but applied to predefined primitive
	operations.
	(Set_Signature): New subprogram used to store the signature of a DT.
	(Displace): If the Offset_To_Top value is not static then call the
	function generated by the expander to get such value; otherwise use
	the value stored in the table of interfaces.
	(Offset_To_Top): The type of the actual has been changed to Address to
	give the correct support to tagged types with discriminants. In this
	case this value is stored just immediately after the tag field.
	(Set_Offset_To_Top): Two new formals have been added to indicate if the
	offset_to_top value is static and hence pass this value to the run-time
	to store it in the table of interfaces, or else if this value is dynamic
	and then pass to the run-time the address of a function that is
	generated by the expander to provide this value for each object of the
	type.

	* rtsfind.ads (Default_Prin_Op_Count): Removed.

	* exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
	Make_Adjust_Call done for a newly-allocated object.

	* exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
	in a subprogram are wrapped in a cleanup block, indicate that the
	subprogram contains an inner block with an exception handler.
	(Make_Adjust_Call): New Boolean formal Allocator indicating whether the
	Adjust call is for a newly-allocated object. In that case we must not
	assume that the finalization list chain pointers are correct (since they
	come from a bit-for-bit copy of the original object's pointers) so if
	the attach level would otherwise be zero (no change), we set it to 4
	instead to cause the pointers to be reset to null.

	* s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
	reset chain pointers to null.

2006-02-13  Ed Schonberg  <schonberg@adacore.com>

	* exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
	string, and the context requires a loop for the assignment (e.g.
	because the left-hand side is packed), generate a unique name for the
	temporary that holds the string, to prevent spurious name clashes.

	* exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
	return unconstrained arrays.
	Update comments.
	(Expand_Call):  An indirect call through an access parameter of a
	protected operation is not a protected call.
	Add circuit to raise CE in Ada 2005 mode following call
	to Raise_Exception.
	(Register_DT_Entry): Do nothing if
	the run-time does not give support to abstract interfaces.
	(Freeze_Subprogram): In case of dispatching operations, do not generate
	code to register the operation in the dispatch table if the source
	is compiled with No_Dispatching_Calls.
	(Register_Predefined_DT_Entry): Generate code that calls the new
	run-time subprogram Set_Predefined_Prim_Op_Address instead of
	Set_Prim_Op_Address.

	* sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
	on array assignments if the right-hand side is a function call that has
	been inlined. Check is performed on the assignment in the block.
	(Process_Bounds): If bounds and range are overloaded, apply preference
	rule for root operations to disambiguate, and diagnose true ambiguity.
	(Analyze_Assignment): Propagate the tag for a class-wide assignment with
	a tag-indeterminate right-hand side even when Expander_Active is True.
	Needed to ensure that dispatching calls to T'Input are allowed and
	get the tag of the target class-wide object.

	* sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
	an inherited primitive operation that already overrides several
	abstract interface primitives. For transitivity, the new entity must
	also override all the abstract interface primitives covered by the
	inherited overriden primitive.
	Emit warning if new entity differs from homograph in same scope only in
	that one has an access parameter and the other one has a parameter of
	a general access type with the same designated type, at the same
	position in the signature.
	(Make_Inequality_Operator): Use source locations of parameters and
	subtype marks from corresponding equality operator when creating the
	tree structure for the implicit declaration of "/=". This does not
	change anything in behaviour except that the decoration of the
	components of the subtree created for "/=" allows ASIS to get the
	string images of the corresponding identifiers.
	(Analyze_Return_Statement): Remove '!' in warning message.
	(Check_Statement_Sequence): Likewise.
	(Analyze_Subprogram_Body): For an access parameter whose designated type
	is an incomplete type imported through a limited_with clause, use the
	type of the corresponding formal in the body.
	(Check_Returns): Implicit return in No_Return procedure now raises
	Program_Error with a compile time warning, instead of beging illegal.
	(Has_Single_Return):  Function returning unconstrained type cannot be
	inlined if expression in unique return statement is not an identifier.
	(Build_Body_To_Inline): It is possible to inline a function call that
	returns an unconstrained type if all return statements in the function
	return the same local variable. Subsidiary procedure Has_Single_Return
	verifies that the body conforms to this restriction.

	* sem_res.adb (Resolve_Equality_Op): If the operands do not have the
	same type, and  one of them is of an anonymous access type, convert
	the other operand to it, so that this is a valid binary operation for
	gigi.
	(Resolve_Type_Conversion): Handle subtypes of protected types and
	task types when accessing to the corresponding record type.
	(Resolve_Allocator): Add '\' in 2-line warning message.
	Remove '!' in warning message.
	(Resolve_Call): Add '\' in 2-line warning message.
	(Valid_Conversion): Likewise.
	(Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
	resulting type may be an access type with an implicit dereference.
	Obtain the proper component from the designated type.
	(Make_Call_Into_Operator): Handle properly a call to predefined equality
	given by an expanded name with prefix Standard, when the operands are
	of an anonymous access type.
	(Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
	Explicit_Dereference and Resolve_Selected_Component, to verify that the
	prefix of the expression is not of an incomplete type. Allows full
	diagnoses of all semantic errors.
	(Resolve_Actuals): If the actual is an allocator whose directly
	designated type is a class-wide interface we build an anonymous
	access type to use it as the type of the allocator. Later, when
	the subprogram call is expanded, if the interface has a secondary
	dispatch table the expander will add a type conversion to force
	the displacement of the pointer.
	(Resolve_Call): If a function that returns an unconstrained type is
	marked Inlined_Always and inlined, the call will be inlined and does
	not require the creation of a transient scope.
	(Check_Direct_Boolean_Op): Removed
	(Resolve_Comparison_Op): Remove call to above
	(Resolve_Equality_Op): Remove call to above
	(Resolve_Logical_Op): Inline above, since this is only call.
	(Valid_Conversion): Handle properly conversions between arrays of
	convertible anonymous access types.

	PR ada/25885
	(Set_Literal_String_Subtype): If the lower bound is not static, wrap
	the literal in an unchecked conversion, because GCC 4.x needs a static
	value for a string bound.

	* exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
	components of the corresponding record, take into account component
	definitions that are access definitions.
	(Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
	procedure is not considered a dispatching call and will be expanded
	properly.

2006-02-13  Javier Miranda  <miranda@adacore.com>

	* exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
	controlling argument of the dispatching call is an abstract interface
	class-wide type then we use it directly.
	Check No_Dispatching_Calls restriction.
	(Default_Prim_Op_Position): Remove the code that looks for the last
	entity in the list of aliased subprograms. This code was wrong in
	case of renamings.
	(Fill_DT_Entry): Add assertion to avoid the use of this subprogram
	when the source is compiled with the No_Dispatching_Calls restriction.
	(Init_Predefined_Interface_Primitives): No need to inherit primitives
	if we are compiling with restriction No_Dispatching_Calls.
	(Make_Disp_XXX): Addition of assertion to avoid the use of all these
	subprograms if we are compiling under No_Dispatching_Calls restriction.
	(Make_DT): Generate a dispatch table with a single dummy entry if
	we are compiling with the No_Dispatching_Calls restriction. In
	addition, in this case we don't generate code that calls to the
	following run-time subprograms: Set_Type_Kind, Inherit_DT.
	(Make_Select_Specific_Data_Table): Add assertion to avoid the use
	of this subprogram if compiling with the No_Dispatching_Calls
	restriction.
	(Expand_Type_Conversion): Instead of using the actual parameter,
	the argument passed as parameter to the conversion function was
	erroneously referenced by the expander.
	(Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
	Set_Predefined_Primitive_Op_Address and Set_Signature.
	(Expand_Dispatching_Call): Generate call to
	Get_Predefined_Prim_Op_Address for predefined primitives.
	(Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
	predefined primitives.
	(Make_DT, Make_Secondary_DT): If the tagged type has no user defined
	primitives we reserve one dummy entry to ensure that the tag does not
	point to some memory that is associated with some other object. In
	addition, remove all the old code that generated the assignments
	associated with the signature of the dispatch table and replace them
	by a call to the new subprogram Set_Signature.
	(Set_All_DT_Position): Change the algorithm because now we have a
	separate dispatch table associated with predefined primitive operations.
	(Expand_Interface_Conversion): In case of non-static offset_to_top
	add explicit dereference to get access to the object after the call
	to displace the pointer to the object.
	(Expand_Interface_Thunk): Modify the generation of the actual used
	in the calls to the run-time function Offset_To_Top to fulfil its
	new interface.
	(Make_DT): Add the new actuals required to call Set_Offset_To_Top.

	* exp_dist.adb (Copy_Specification): For access parameters, copy
	Null_Exclusion flag, which will have been set for stream subprograms
	in Ada2005 mode.

2006-02-13  Pascal Obry  <obry@adacore.com>

	* expect.c (__gnat_expect_portable_execvp): New implementation. The
	previous implementation was using the C runtime spawnve routine but
	the corresponding wait was using directly the Win32 API. This was
	causing some times a lock when waiting for an event using
	WaitForSingleObject in __gnat_waitpid. This new implementation uses
	the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
	API fixes this problem.

	reanalysis from resetting its type to the original (non-packed) array
	type.

	are copied at the point of reference, and therefore must be marked as
	renamings of objects.

	(Image) [Natural]: The parameter was an Integer, as we can't deal with
	negative numbers (years, months...) it is better to have a Natural here.
	Code clean-up.
	(Image) [Number]: Change parameter from Long_Integer to Number.
	(Image): Use Number type to compute the seconds since 1-1-1970 to fix an

	(Check_Private_Child_Unit): Move test for a nonprivate with clause down

	This ensures that private with clauses are not exempted from the basic
	checking for being a descendant of the same library unit parent as a
	withed private descendant unit.
	(Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
	handle private with clauses properly, as well as to account for cases
	where the withed unit is a public descendant of a private ancestor

	Parameter and variable names improved for readability.
	(Install_Limited_Context_Clauses): Remove test for a withed unit being
	private as the precondition for calling

	Document that pragma Propagate_Exceptions has no effect
	(Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
	(Set_Convention_From_Pragma): Check that if a convention is
	specified for a dispatching operation, then it must be
	consistent with the existing convention for the operation.
	(CPP_Class): Because of the C++ ABI compatibility, the programmer is no
	longer required to specify an vtable-ptr component in the record. For
	compatibility reasons we leave the support for the previous definition.
	(Analyze_Pragma, case No_Return): Allow multiple arguments

	* sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
	non-overrideen inherited operation with a controlling result as
	illegal only its implicit declaration comes from the derived type
	declaration of its result's type.
	(Check_Possible_Deferred_Completion): Relocate the object definition
	node of the subtype indication of a deferred constant completion rather
	than directly analyzing it. The analysis of the generated subtype will
	correctly decorate the GNAT tree.
	(Record_Type_Declaration): Check whether this is a declaration for a
	limited derived record before analyzing components.
	(Analyze_Component_Declaration): Diagnose record types  not explicitly
	declared limited when a component has a limited type.
	(Build_Derived_Record_Type): Code reorganization to check if some of
	the inherited subprograms of a tagged type cover interface primitives.
	This check was missing in case of a full-type associated with a private
	type declaration.
	(Constant_Redeclaration): Check that the subtypes of the partial and the
	full view of a constrained deferred constant statically match.
	(Mentions_T): A reference to the current type in an anonymous access
	component declaration  must be an entity name.
	(Make_Incomplete_Type_Declaration): If type is tagged, set type of
	class_wide type to refer to full type, not to the incomplete one.
	(Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
	available. Required to give support to the certified run-time.
	(Analyze_Component_Declaration): In case of anonymous access components
	perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
	(Process_Discriminants): For an access discriminant, use the
	discriminant specification as the associated_node_for_itype, to
	simplify accessibility checks.

	    Javier Miranda  <miranda@adacore.com>

	* sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
	abstract interpretations on an operator, remove interpretations that
	yield Address or a type derived from it, if one of the operands is an
	integer literal.
	(Try_Object_Operation.Try_Primitive_Operation,
	Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
	location when creating the new reference to a primitive or class-wide
	operation as a part of rewriting a subprogram call.
	(Try_Primitive_Operations): If context requires a function, collect all
	interpretations after the first match, because there may be primitive
	operations of the same type with the same profile and different return
	types. From code reading.
	(Try_Primitive_Operation): Use the node kind to choose the proper
	operation when a function and a procedure have the same parameter
	profile.
	(Complete_Object_Operation): If formal is an access parameter and prefix
	is an object, rewrite as an Access reference, to match signature of
	primitive operation.
	(Find_Equality_Type, Find_One_Interp): Handle properly equality given
	by an expanded name with prefix Standard, when the operands are of an
	anonymous access type.
	(Remove_Abstract_Operations): If the operation is abstract because it is
	inherited by a user-defined type derived from Address, remove it as
	well from the set of candidate interpretations of an overloaded node.
	(Analyze_Membership_Op): Membership test not applicable to cpp-class
	types.

2006-02-13  Bob Duff  <duff@adacore.com>

	* sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
	redundant use clauses.
	In particular, if the scope of two use clauses overlaps, but one is not
	entirely included in the other, we should not warn.  This can happen
	with nested packages.
	(Analyze_Subprogram_Renaming): Protect the compiler against previously
	reported errors. The bug was reported when the compiler was built
	with assertions enabled.
	(Find_Type): If the node is a 'Class reference and the prefix is a
	synchronized type without a corresponding record, return the type
	itself.

2006-02-13  Javier Miranda  <miranda@adacore.com>

	* sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
	if this is the full-declaration associated with a private declaration
	that implement interfaces, then the private type declaration must be
	limited.
	(Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
	as aliased. The use of the 'access attribute is not available for such
	object (for this purpose the object should be explicitly marked as
	aliased, but being an anonymous type this is not possible).

2006-02-13  Ed Schonberg  <schonberg@adacore.com>
	    Robert Dewar  <dewar@adacore.com>

	* sem_elab.adb (Same_Elaboration_Scope): A package that is a
	compilation unit is an elaboration scope.
	(Add_Task_Proc): Add '\' in 2-line warning message.

2006-02-13  Ed Schonberg  <schonberg@adacore.com>
	    Javier Miranda  <miranda@adacore.com>

	* sem_type.adb (Write_Overloads): Improve display of candidate
	interpretations.
	(Add_One_Interp): Do not add to the list of interpretations aliased
	entities corresponding with an abstract interface type that is an
	immediate ancestor of a tagged type; otherwise we have a dummy
	conflict between this entity and the aliased entity.
	(Disambiguate): The predefined equality on universal_access is not
	usable if there is a user-defined equality with the proper signature,
	declared in the same declarative part as the designated type.
	(Find_Unique_Type): The universal_access equality operator defined under
	AI-230 does not cover pool specific access types.
	(Covers): If one of the types is a generic actual subtype, check whether
	it matches the partial view of the other type.

2006-02-13  Thomas Quinot  <quinot@adacore.com>

	* sinput-d.adb (Write_Line): Update the Source_Index_Table after each
	line. This is necessary to allow In_Extended_Main_Unit to provide
	correct results for itypes while writing out expanded source.

	now done for each line.

2006-02-13  Bob Duff  <duff@adacore.com>

	* s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
	Scan_Unsigned, so we do not scan leading blanks and sign twice.
	Integer'Value("- 5") and Integer'Value("-+5") now correctly
	raise Constraint_Error.

	* s-vallli.adb (Scan_Long_Long_Integer): Call
	Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
	do not scan leading blanks and sign twice.
	Integer'Value("- 5") and Integer'Value("-+5") now correctly
	raise Constraint_Error.

	* s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
	Scan_Long_Long_Unsigned): Split out most of the processing from
	Scan_Long_Long_Unsigned out into
	Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
	This prevents scanning leading blanks and sign twice.
	Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
	See RM-3.5(44).

	* s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
	out most of the processing from Scan_Unsigned out into
	Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
	This prevents scanning leading blanks and sign twice.

	* s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
	use with Modular'Value attribute.

	* a-taster.ads, a-taster.adb: New files.

	* a-elchha.adb (Last_Chance_Handler): Change the task termination soft

	* a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
	handler because of an unhandled exception.

	* a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

	* s-finimp.adb (initialization code): Modify the soft link for the
	finalization of the global list instead of Adafinal.

	* s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
	non-tasking version of the soft link for task termination. We do
	nothing since if we are using the non-tasking version it
	means that the task termination functionality is not used.
	(Null_Finalize_Global_List): Add this null version for the procedure
	in charge of finalizing the global list for controlled objects.
	(Null_Adafinal): Remove this procedure. Adafinal_NT has been created
	instead for handling run-time termination in a more flexible way.
	(Adafinal_NT): This new procedure will take care of finalizing the
	global list for controlled objects if needed, but no tasking
	finalization.

	* s-tarest.adb (Task_Lock): Do not try to lock again the
	Global_Task_Lock if we already own it. Otherwise, we get blocked in
	some run-time operations.
	(Task_Unlock): Do not try to actually unlock the Global_Task_Lock

	Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
	Common_ATCB because it is used by both the regular and the restricted
	run times.
	(Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
	Common_ATCB because it is used by both the regular and the restricted
	run times.

	(Task_Wrapper): added dynamic stack analysis.

	* s-tasuti.adb (Abort_Tasks): The code in charge of checking
	potentially blocking operations has been moved from
	System.Tasking.Stages.Abort_Tasks to this procedure. There can be
	direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
	through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
	this run-time check.

	* s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
	of task termination procedure.
	(Init_Tasking_Soft_Links): Install the task-safe version of the soft

	* a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body

	(Set_Interface_Table): Add missing assertion.
	Update documentation describing the run-time structure.
	(Displace): New subprogram that displaces the pointer to the object
	to reference one of its secondary dispatch tables.
	(IW_Membership): Modified to use the new table of interfaces.
	(Inherit_TSD): Modified to use the new table of interfaces.

	(Get_Num_Prim_Ops, Set_Num_Prim_Ops): Remove an unnecessary type
	conversion.
	(Get_Tagged_Kind, Set_Tagged_Kind): New bodies.

	* exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
	in all the calls to Expand_Interface_Thunk. Instead of referencing the
	record component containing the tag of the secondary dispatch table we
	have to use the Offset_To_Top run-time function to get this information;
	otherwise if the pointer to the base of the object has been displace
	we get a wrong value if we use the 'position attribute.

	* exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
	all the calls to Expand_Interface_Thunk.
	(Make_Secondary_DT): Secondary dispatch tables do not have a table of
	interfaces; hence the call to Set_Interface_Table was clearly wrong.
	(Collect_All_Interfaces): Modify the internal subprogram Collect to
	ensure that the interfaces implemented by the ancestors are placed
	at the header of the generated list.
	(Expand_Interface_Conversion): Handle the case in which the displacement
	associated with the interface conversion is not statically known. In
	this case we generate a call to the new run-time subprogram Displace.
	(Make_DT): Generate and fill the new table of interfaces.
	(Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
	Get_Tagged_Kind and Set_Tagged_Kind.

	with respect to limitedness and concurrency and returns a reference to
	RE_Tagged_Kind.
	(Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
	Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
	primary dispatch table for a type.

	secondary dispatch table respectively of a tagged type.

	* exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.

	from a fat or thin pointer type and a constrained object type.
	(build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
	types variants, and process special cases of VIEW_CONVERT expressions
	as their NOP_EXPR counterpart to ensure we get to the
	CORRESPONDING_VARs associated with CONST_DECls.
	(build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
	on the right-hand side.

	SIZE and SIZE_UNIT which we need for later back-annotations.

	'Class reference, it is tagged, and its list of primitive operations
	must be initialized properly.
	(Chain_Use_Clauses): When chaining the use clauses that appear in the

	* sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
	'Address attribute reference with an overloaded prefix, use the
	location of the prefix (not the location of the attribute reference) as
	the error location.
	(Analyze_Attribute, case 'Size): The name of an enumeration literal, or
	a function renaming thereof, is a valid prefix for 'Size (where it is
	intepreted as a function call).
	(Statically_Denotes_Entity): New predicate to determine whether the

	* sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
	become local to the whole package.
	(Install_Limited_Withed_Unit): Instead of unchaining real entities if
	the package was already analyzed the new algorithm "replaces" the
	real entities by the shadow ones. This is required to ensure that
	the order of these entities in the homonym chains does not change;
	otherwise we can have undefined references at linking time because
	in case of conflicts the external name of the entities will have
	a suffix that depends on the order of the entities in the chain.
	(Remove_Limited_With_Clause): Complementary code that completes the
	new algorithm and replaces the shadow entities by the real ones.
	(Install_Limited_Withed_Unit): When unchaining entities before the
	installation of the shadow entities, only regular entities of the
	public part must be taken into account. This is required to
	keep this routine in synch with the work done by Remove_Limited_
	With_Clause
	(Install_Limited_With_Clause): Introduce implicit limited_with_clause
	even if unit is analyzed, because the analysis of the unit is
	idempotent in any case, and the limited view of the unit may have to
	be installed for proper visibility.
	(Expand_Limited_With_Clause): Even if the unit in the implicit
	with_clause has been analyzed already, a limited view of the package
	must be built for the current context, if it does not exist yet.

	    Gary Dismukes  <dismukes@adacore.com>

	* sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
	defining entity for the instance body, make a new defining identifier
	rather than copying the entity of the spec, to prevent accidental
	sharing of the entity list.
	(Check_Private_View): When exchanging views of private types, build the
	list of exchanged views as a stack, to ensure that on exit the exchanges
	are undone in the proper order.
	(Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
	Restore the compilation environment in case of instantiation_error.
	(Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
	for an anonymous access result.
	(Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition

	denotes a generic package renaming.

2005-09-01  Thomas Quinot  <quinot@adacore.com>

	    Ed Schonberg  <schonberg@adacore.com>
	    Javier Miranda  <miranda@adacore.com>

	* sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
	underlying type
	to check if a type is Constrained in cases related to code generation
	(rather than semantic checking) since otherwise we do not generate
	similar code for mutable private types depending if their
	discriminants are visible or not.
	(Check_Abstract_Overriding): Do not complain about failure to override
	the primitive operations used in dispatching selects since they will
	always be overriden at the freeze point of the type.
	(Access_Definition): Separate out handling for resetting the scope
	of an anonymous access function result type. Retrieve the scope
	of the associated function rather than using Current_Scope, which
	does not have a consistent value (depends on whether we're in the
	middle of analyzing formal parameters). Add ??? comment about
	finding a cleaner way to handle the special cases of scope setting.
	(Process_Incomplete_Dependents): A protected operation is never a
	dispatching operation (only its wrapper may be).
	(Build_Derived_Record_Type): In case of tagged private types that
	implement interfaces add derivation of predefined primitive
	operations.
	(Derive_Subprograms): Replace the Is_Interface_Derivation parameter
	by two parameters that are used in case of derivation from abstract
	interface types: No_Predefined_Prims is used to avoid the derivation
	of predefined primitives from the interface, and Predefined
	Prims_Only is used to complete the derivation predefined primitives
	in case of private tagged types implementing interfaces.
	Fix typo in comments
	(Find_Interface_In_Descendant): Protect the frontend against
	wrong code with large circularity chains.
	(Is_Private_Overriding): Add support for entities overriding interface
	subprograms. The test failed because Entities associated with overriden
	interface subprograms are always marked as hidden (and used to build
	the secondary dispatch table); in this case the overriden entity is
	available through the field abstract_interface_alias (cf. override_
	dispatching_operation)
	(Access_Definition): Set the scope of the type to Current_Scope for the
	case of a function with an anonymous access result type.
	(Access_Subprogram_Declaration): Handle creation of the type entity for
	an access-to-function type with an anonymous access result.
	(Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
	in handling for N_Access_Function_Definition.
	(Analyze_Subtype_Declaration): Modify the text of error message.
	(Derived_Type_Declaration): Modify the text of error message.
	(Process_Subtype): Modify the text of error message plus cleanup
	of one redundant error message.
	(Analyze_Component_Declaration): Code cleanup.
	(Analyze_Object_Declaration): Code cleanup.
	(Analyze_Subtype_Declaration): Propagate the null-exclusion
	attribute in case of access types. Code cleanup.
	(Array_Type_Declaration): Code cleanup.
	(Process_Discriminants): Create the new null-excluding itype
	if required. Code cleanup.
	(Process_Subtype): Create the new null-excluding itype if
	required. Code cleanup.
	(Build_Derived_Record_Type): Code cleanup to avoid calling
	twice the subprogram derive_subprograms in case of private
	types that implement interfaces. In this particular case the
	subprogram Complete_Subprograms_Derivation already does the
	job associated with the second call.

	* exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
	conversion to the full view when generating an operation for a
	discriminant whose type may currently be private.

2005-09-01  Ed Schonberg  <schonberg@adacore.com>
	    Javier Miranda  <miranda@adacore.com>

	* sem_ch4.adb (Transform_Object_Operation): In a context off the form
	V (Obj.F), the rewriting does not involve the indexed component, but
	only the selected component itself.
	Do not apply the transformation if the analyzed node is an actual of a
	call to another subprogram.
	(Complete_Object_Operation): Retain the entity of the
	dispatching operation in the selector of the rewritten node. The
	entity will be used in the expansion of dispatching selects.
	(Analyze_One_Call): Improve location of the error message associated
	with interface.
	(Analyze_Selected_Component): No need to resolve prefix when it is a
	function call, resolution is done when parent node is resolved, as
	usual.
	(Analyze_One_Call): Add a flag to suppress analysis of the first actual,
	when attempting to resolve a call transformed from its object notation.
	(Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
	of the argument list for each interpretation of the operation.
	(Try_Object_Operation): The designated type of an access parameter may
	be an incomplete type obtained through a limited_with clause, in which
	case the primitive operations of the type are retrieved from its full
	view.
	(Analyze_Call): If this is an indirect call, and the return type of the
	access_to_subprogram is incomplete, use its full view if available.

2005-09-01  Javier Miranda  <miranda@adacore.com>
	    Gary Dismukes  <dismukes@adacore.com>

	* sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
	access types the null-exclusion and access-to-constant attributes must
	also match.
	(Analyze_Return_Statement): When the result type is an anonymous access
	type, apply a conversion of the return expression to the access type
	to ensure that appropriate accessibility checks are performed.
	(Analyze_Return_Type): For the case of an anonymous access result type,
	generate the Itype and set Is_Local_Anonymous_Access on the type.
	Add ??? placeholder for check to disallow returning a limited object
	in Ada 2005 unless it's an aggregate or a result of a function call.
	Change calls from Subtype_Mark to Result_Definition.
	(Analyze_Subprogram_Body): Change formal Subtype_Mark to
	Result_Definition in call to Make_Function_Specification.
	(Build_Body_To_Inline): Change Set_Subtype_Mark to
	Set_Result_Definition.
	(Make_Inequality_Operator): Change formal Subtype_Mark to
	Result_Definition in call to Make_Function_Specification.
	(Process_Formals): Create the new null-excluding itype if required.
	(New_Overloaded_Entity): For an entity overriding an interface primitive
	check if the entity also covers other abstract subprograms in the same
	scope. This is required to handle the general case, that is, overriding
	other interface primitives and overriding abstract subprograms inherited
	from some abstract ancestor type.
	(New_Overloaded_Entity): For an overriding entity that comes from
	source, note the operation that it overrides.
	(Check_Conformance, Type_Conformant): Addition of one new formal
	to skip controlling formals in the analysis. This is used to
	handle overloading of abstract interfaces.
	(Base_Types_Match): Add missing case for types imported from
	limited-with clauses
	(New_Overloaded_Entity): Add barrier to protect the use of
	the "alias" attribute.

2005-09-01  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
	verify that the procedure and the entry are mode conformant.
	(Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
	as a different operator, which is often a cut-and-paste error.

	    Ed Schonberg  <schonberg@adacore.com>

	* sem_disp.adb (Check_Controlling_Formals): Anonymous access types
	used in controlling parameters exclude null because it is necessary to
	read the tag to dispatch, and null has no tag.
	(Override_Dispatching_Operation): If the previous operation is inherited
	from an interface, it becomes hidden  and does not participate in later
	name resolution.

	* sem_res.adb (Resolve_Membership_Op): In case of the membership test
	"Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
	the expander will generate the corresponding run-time check to evaluate
	the expression.
	(Resolve_Call): Check for legal type of procedure name or prefix that
	appears as a trigger in a triggering alternative.
	(Valid_Conversion): If expression is ambiguous and the context involves
	an extension of System, remove System.Address interpretations.
	(Resolve_Qualified_Expression): Reject the case of a specific-type
	qualification applied to a class-wide argument. Enhance comment
	to explain checking of Original_Node.
	(Resolve_Type_Conversion): The location of the error message was not
	general enough to handle the general case and hence it has been removed.
	In addition, this patch improves the text of the message.
	(Resolve_Type_Conversion): Add missing support for access to interface
	types.
	(Resolve_Type_Conversion): If the target is a class-wide interface type,
	do not expand if the expression is the actual in a call, because proper
	expansion will take place when the call itself is expanded.
	(Resolve_Allocator): If the context is an unchecked conversion, the
	allocator inherits its storage pool, if any, from the target type of
	the conversion.

	* sem_type.adb (Add_One_Interp): If a candidate operation is an
	inherited interface operation that has an implementation, use the
	implementation to avoid spurious ambiguities.
	(Interface_Present_In_Ancestor): In case of concurrent types we can't
	use the Corresponding_Record_Typ attribute to look for the interface
	because it is set by the expander (and hence it is not always
	available). For this reason we traverse the list of interfaces
	(available in the parent of the concurrent type).

	parameter.
	(Is_Renamed_Entry): Determine whether an entry is a procedure renaming
	of an entry.
	(Safe_To_Capture_Value): A value (such as non_null) is not safe to
	capture if it is generated in the second operand of a short-circuit
	operation.
	Do not capture values for variables with address clauses.
	(Is_Object_Reference): Treat a function call as an object reference only
	if its type is not Standard_Void_Type.

	    Thomas Quinot  <quinot@adacore.com>

	* gnat_rm.texi: Add a note that pragma Unreferenced is not appropriate
	if the user wants all calls of a subprogram to be flagged,
	independently of whether they are made from within the same unit or
	another unit.
	Mention restriction for pragma Linker_Alias on some platforms.
	Document pragma Linker_Constructor and Linker_Destructor.
	Rewrite documentation of Weak_External, Linker_Section and
	Linker_Alias pragmas.

2005-07-04  Arnaud Charlet  <charlet@adacore.com>

	* s-stausa.ads, s-stausa.adb: New files.

2005-06-30  Kelley Cook

	* all files:  Update FSF address in copyright headers.
	* gen-soccon.co (main): Output new FSF address in generated files.

2005-06-28  Paul Brook  <paul@codesourcery.com>

	* misc.c (gnat_init_gcc_eh): Call default_init_unwind_resume_libfunc.

	    Eric Botcazou  <ebotcazou@adacore.com>

	* s-mastop-irix.adb (Pop_Frame): Revert shorcuts avoiding calls to
	exc_unwind, now that we are generating proper .debug_frame output for
	that target.

	* tracebak.c: Remove the mips-irix section, as we are now using the
	s-mastop based unwinder again.
	Under SPARC/Solaris, take into account the stack bias to compute the
	frame offset.  The stack bias is 0 for the V8 ABI and 2047 for the V9
	ABI.

	    Arnaud Charlet  <charlet@adacore.com>

	* a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
	longer protected objects. They have been replaced by lower-level
	suspension objects made up by a mutex and a condition variable (or
	their equivalent given a particular OS) plus some internal data to
	reflect the state of the suspension object.
	(Initialize, Finalize): Add this initialization procedure for
	Suspension_Object, which is a controlled type.
	(Finalize): Add the finalization procedure for Suspension_Object,
	which is a controlled type.

	* a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
	Ada.Synchronous_Task_Control because there is no longer a need for a
	VxWorks specific version of this package. Target dependencies
	has been moved to System.Task_Primitives.Operations.

	* s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
	longer needed.
	(InitializeCriticalSection, EnterCriticalSection,
	LeaveCriticalSection, DeleteCriticalSection): Replace the type
	pCriticalSection by an anonymous access type so that we avoid problems
	of accessibility to local objects.

	* s-taprop.ads, s-taprop-posix.adb, s-taprop-vxworks.adb,
	s-taprop-mingw.adb, s-taprop-vms.adb, s-taprop-solaris.adb,

	s-taprop-linux.adb, s-taprop-irix.adb, s-taprop-irix-athread.adb,
	s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
	set the environment task mask here.
	(Current_State): Add this function that returns the state of the
	suspension object.
	(Set_False): Add this procedure that sets the state of the suspension
	object to False.
	(Set_True): Add this procedure that sets the state of the suspension
	object to True, releasing the task that was suspended, if any.
	(Suspend_Until_True): Add this procedure that blocks the calling task
	until the state of the object is True. Program_Error is raised if
	another task is already waiting on that suspension object.
	(Initialize): Add this procedure for initializing the suspension
	object. It initializes the mutex and the condition variable which are
	used for synchronization and queuing, and it sets the internal state
	to False.
	(Finalize): Add this procedure for finalizing the suspension object,
	destroying the mutex and the condition variable.

	* s-taspri-posix.ads, s-taspri-vxworks.ads, s-taspri-mingw.ads,
	s-taspri-vms.ads, s-taspri-solaris.ads, s-taspri-os2.ads,
	s-taspri-dummy.ads, s-taspri-hpux-dce.ads, s-taspri-linux.ads,
	s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
	which provides a low-level abstraction (using operating system
	primitives) for Ada.Synchronous_Task_Control.
	This object is made up by a mutex (for ensuring mutual exclusion), a
	condition variable (for queuing threads until the condition is
	signaled), a Boolean (State) indicating whether the object is open,
	and a Boolean (Waiting) reflecting whether there is a task already
	suspended on this object.

	* s-intman.ads, s-intman-irix.adb, s-intman-irix-athread.adb,
	s-intman-dummy.adb, s-intman-solaris.adb, s-intman-vms.adb,

	(Initialize_Interrupts): Removed, no longer used.

	* s-inmaop-posix.adb, s-inmaop-vms.adb, s-inmaop-dummy.adb,
	(Setup_Interrupt_Mask): New procedure.

	* s-intman-vxworks.ads, s-intman-vxworks.adb:  Update comments.

	* s-inmaop.ads (Setup_Interrupt_Mask): New procedure

	* s-interr.adb: Add explicit call to Setup_Interrupt_Mask now that
	this is no longer done in the body of s-taprop
	(Server_Task): Explicitely test for Pending_Action in case
	System.Parameters.No_Abort is True.

	* s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
	is no longer done in the body of s-taprop

	such discriminants have their accessibility level defined in the same
	way as a normal component of an anonymous access type.

	constant-folded, there is nothing to check.
	(Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer

	as the name of the appropriate compiler-generated stream primitive.

	forbid conversion of a local access-to-subprogram type to a remote one.

	* sem_util.adb (Wrong_Type): For a record type that is the expanded
	equivalent type for a remote access-to-subprogram type, go back to the

	with the expected type.

	access to subprogram, do not rewrite node as a call.

	the node as a call once the context identifies the interpretation of
	the prefix whose call yields the context type.
	(Valid_Conversion): For the case of a conversion between
	local access-to-subprogram types, check subtype conformance using
	Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
	detailed error message.

2005-03-29  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
	indicator, indicate that the formal can never be null.
	(Process_Formals): If a formal has a non_null indicator, insert the
	resulting subtype immediately before the enclosing subprogram decl,

	Currently we don't permit this, but this is under discussion by the
	ARG, and it is easy enough to use a different example.

	* s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
	handling UTF-32 encoding for wide wide character.

	describing the new layout.
	(Dispatch_Table): The expander computes the actual array size, allocates

	(Analyze_Subprogram_Body): Warn on inlining bodies with nested
	subprogram only if inner one comes from source.
	(Analyze_Function_Call): If the call is given in object notation, the
	analysis of the name rewrites the node and analyzes it with the proper
	argument list. After analyzing the name, if the call has been rewritten
	and the result type is set, no further analysis is needed.
	(Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
	mark in function specification, in a context where the formals are
	visible and hide outer homographs.

	* sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
	as the tagged type for the cases of abstract formal subprograms and
	renamings of those.  Clean up spec comments.
	(Check_Dispatching_Context): Add error message to indicate "abstract

	that has statically tagged operands.
	(Check_Dispatching_Call): Check for the case of an actual given by
	a tag-indeterminate function call whose type is an ancestor of the
	containing call's associated tagged type. This situation can occur

	the calls.

	SEH (Structured Exception Handling) now.
	(__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.

	(Operator_Check): Always use the first subtype in the
	error message, to avoid the appearance of internal base types.
	(Transform_Object_Operation): Copy each actual in full
	to the parameter associations of the constructed call, rather than
	using the shallow copy mechanism of New_Copy_List. This ensures that

	* sem_util.adb (Insert_Explicit_Dereference): When an implicit
	dereference is rewritten to an explicit one, generate a reference to
	the entity denoted by its prefix using the original prefix node, so

	emitting 'assigned but never read' warning on a variable on the basis
	that it has an access type.

	subprogram which is Imported with convention Intrinsic if an
	External_Name argument is specified.
	(Process_Import_Or_Interface): Properly diagnose link name argument.
	(Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
	with Sem_Ch6.Cannot_Inline.
	(Process_Inline): Provide separate warning for inapplicable inline
	pragma.

	Make_Index.

2004-12-07  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

	* gigi.h (others_decl, all_others_decl): New decls representing the
	new Others_Value and All_Others_Value objects.

	corresponding objects exported by a-exexpr, instead of hardcoded dummy
	addresses.

	* trans.c (Exception_Handler_to_gnu_zcx): Use the address of
	others_decl and all_others_decl instead of hardcoded dummy addresses
	to represent "others" and "all others" choices, which is cleaner and
	more flexible with respect to the possible eh pointer encoding policies.

	* utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
	(process_attributes): Account for the naming change of the "args"

	* exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
	function with string.
	Use new Has_Rep_Pragma function.

	* tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
	string argument.

2004-11-18  Robert Dewar  <dewar@adacore.com>

	* errout.ads, errout.adb: (First_Sloc): New function

	* par-ch5.adb (P_Condition): Check for redundant parens is now a style
	check (-gnatyx) instead of being included as a redundant construct
	warning.

	* sem_ch6.adb: Change name Style_Check_Subprogram_Order to
	Style_Check_Order_Subprograms.

	* style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
	stylesw.adb: Add Style_Check_Xtra_Parens

	* usage.adb: Add line for -gnatyx (check extra parens)

	* vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx

2004-11-18  Ed Schonberg  <schonberg@adacore.com>
	    Robert Dewar  <dewar@adacore.com>

	* exp_ch4.adb (Expand_N_Selected_Component): If the component is the
	discriminant of a constrained subtype, analyze the copy of the
	corresponding constraint, because in some cases it may be only
	partially analyzed.
	Removes long-lived ??? comments.

	* exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
	handled controlled or secondary-stack expressions within the
	iteration_scheme of a loop.

	* sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
	bounds that may contain functions calls, to prevent memory leaks when
	the bound contains a call to a function that uses the secondary stack.
	(Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
	generate temporaries for loop bounds that might contain function calls
	that require secondary stack and/or finalization actions.

	* sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
	selected component and the selector is overloadable (not just a
	function) treat as function call, Analyze_Call will disambiguate if
	necessary.
	(Analyze_Selected_Component): Do not generate an actual subtype for the
	selected component if expansion is disabled. The actual subtype is only
	needed for constraint checks.
	(Analyze_Allocator): If restriction No_Streams is set, then do
	not permit objects to be declared of a stream type, or of a
	composite type containing a stream.

	* restrict.ads: Remove the a-stream entry from Unit_Array, since
	No_Streams no longer prohibits with'ing this package.

	* sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
	discriminants, but the parent base has unknown discriminants, there is
	no discriminant constraint to inherit. Such a discrepancy can arise
	when the actual for a formal type with unknown discriminants is a
	similar private type whose full view has discriminants.
	(Analyze_Object_Declaration): If restriction No_Streams is set, then
	do not permit objects to be declared of a stream type, or of a
	composite type containing a stream.

2004-11-18  Ed Schonberg  <schonberg@adacore.com>

	* exp_dbug.ads: Update documentation to reflect simpler encoding for
	protected operations.

	* exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
	generated name, it complicates decoding in gdb and hinders debugging
	of protected operations.
	(Build_Barrier_Function_Specification): Set the Needs_Debug_Info
	flag for the protected entry barrier function.
	(Build_Protected_Entry_Specification): Set the Needs_Debug_Info
	flag for the protected entry function.

2004-11-18  Nicolas Setton  <setton@adacore.com>

	* expect.c: Define __unix__ when __APPLE__ is defined.

	* Makefile.in: Inform the value of the variable GMEM_LIB in the
	Darwin-specific section.

	* lang-specs.h: Change the placement of the %1 marker.
	Works around the fact that gcc adds -fPIC by default under Darwin.

2004-11-18  Ed Schonberg  <schonberg@adacore.com>

	* exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
	type of the object with the packed array type, set the Analyzed flag
	on the object if it is an entity or simple indexed component, to avoid
	spurious type errors.

2004-11-18  Gary Dismukes  <dismukes@adacore.com>

	* gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
	gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
	separate line from the version message.

2004-11-18  Ed Falis  <falis@adacore.com>

	* init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
	vthreads.
	(init_float): Eliminate initialization of floating point status for
	AE653. The instructions have no effect for vThreads.

2004-11-18  Vincent Celier  <celier@adacore.com>

	* make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
	gnatbind is invoked with -shared.

2004-11-18  Jose Ruiz  <ruiz@adacore.com>

	* s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
	for Detect_Blocking which is redundant with the check done within the
	procedure Protected_Single_Entry_Call.
	(Lock_Read_Only_Entry): Remove the code for raising Program_Error for
	Detect_Blocking which is redundant with the check done within the
	procedure Protected_Single_Entry_Call.

2004-11-18  Vincent Celier  <celier@adacore.com>

	* makegpr.adb (Compile): Put the compiling switches (in package
	Compiler and on the command line) immediately after "-c", instead of
	at the end of the command line invocation of the compiler, when
	compiling a non-Ada file.
	(Build_Global_Archive): When there is no need to rebuild the archive,
	set Global_Archive_Exists, so that the archive is passed to the linker
	if one is needed.

2004-11-18  Robert Dewar  <dewar@adacore.com>
	    Sergey Rybin  <rybin@adacore.com>

	* gnat_ugn.texi:
	Remove extra paren check from list of checks for redundant constructs
	Add documentation of new -gnatyx style check (check extra parens)
	Remove paragraph about gnatelim debug options.

	* gnat_rm.texi: Document that Ada.Streams now forbids creating stream
	objects rather than forbidding dependencies on the package Ada.Streams.

	* sinfo.ads: Add ??? note that we should document pragmas passed to
	back end.

	* g-expect.ads: Fix a few typos in the comments.

2004-11-09  Joseph S. Myers  <joseph@codesourcery.com>

	* misc.c (gnat_handle_option): Use %< and %> for quoting in
	warning message.

2004-11-08  Rainer Orth  <ro@TechFak.Uni-Bielefeld.DE>

	* a-numaux-x86.adb (Tan): Fix fdivp syntax.

2004-11-07  Andreas Schwab  <schwab@suse.de>

	* Makefile.in (install-gnatlib): Remove spurious hyphen.

2004-11-02  Andrew Pinski  <pinskia@physics.uc.edu>

	PR ada/18228
	* Makefile.in (darwin): Set soext to .dylib.

2004-10-26  Vincent Celier  <celier@gnat.com>
	    Thomas Quinot   <quinot@act-europe.fr>

	* g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
	(C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
	there is no use of GNAT.Sockets.Constants.
	Remove remaining pragma Import for C_Write
	Remove C_Read and C_Write from internal implementation unit
	GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
	the read and write functions from the system runtime library is fine
	on UNIX but won't work under Windows).

	* g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
	(Check_Selector): Use C_Recv instead of C_Read.
	Selectors are the GNAT.Sockets abstraction to perform a select()
	call on a set of descriptors. To allow abortion of an ongoing
	select operation, some data is written to a dedicated socket that
	is always monitored.
	Under Windows, the write and read library functions cannot operate
	on sockets, so we need to use send and recv instead, which is portable
	across all supported platforms.

	* g-socthi.ads: Remove C_Read and C_Write from internal implementation
	unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
	(using the read and write functions from the system runtime library is
	fine on UNIX but won't work under Windows).

2004-10-26  Nicolas Setton  <setton@act-europe.fr>

	* mlib-tgt-darwin.adb: New file.

	* mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
	mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
	mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
	mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
	subprogram body.

	* Makefile.in: Add support for building shared libraries under Darwin.
	(EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
	the low level EH init subprogram to be called from __gnat_initialize.

	* mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
	indicates which options to pass to the archive indexer.

	* mlib-utl.adb: Add support for calling ranlib with additional
	options. This is needed for instance under Mac OS X.
	(Ranlib_Options): New global variable, used to store the potential
	options to pass to ranlib.
	(Ar): Use Ranlib_Options when spawning ranlib.
	(Initialize): Set the value of ranlib option.

2004-10-26  Olivier Hainque  <hainque@act-europe.fr>

	* s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
	instead of 8K, to reflect the real potential needs for stack-checking
	in the ZCX case.

2004-10-26  Pascal Obry  <obry@gnat.com>

	* s-parame-mingw.adb (Default_Stack_Size): Add some comments.

	* s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
	Windows only the initial thread stack size can be set so it is good to
	start we a low stack size.
	The OS will adjust the size as needed.

2004-10-26  Olivier Hainque  <hainque@act-europe.fr>
	    Nicolas Setton  <setton@act-europe.fr>

	* expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
	"__unix__" instead of "unix".
	The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
	sections were just mistakenly ignored. The former is
	implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
	Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
	of hpux. This prevents an unwanted definition of the symbol
	convert_addresses in adaint.o.

2004-10-26  Gary Dismukes  <dismukes@gnat.com>

	* a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
	compatibility with type Unwind_Word on 16-bit targets such as AAMP.

2004-10-26  Cyrille Comar  <comar@act-europe.fr>

	* a-filico.ads, a-filico.adb: fix incorrect header.

2004-10-26  Javier Miranda  <miranda@gnat.com>

	* a-ststio.ads: Fix typo in identifier

2004-10-26  Thomas Quinot  <quinot@act-europe.fr>

	* sem_ch4.adb: Minor reformatting.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* checks.adb (Expr_Known_Valid): If floating-point validity checks are
	enabled, check the result of unary and binary operations when the
	expression is the right-hand side of an assignment.

2004-10-26  Vincent Celier  <celier@gnat.com>

	* clean.adb (Delete): Do not output warnings when in quiet output and
	not in verbose mode.
	(Force_Deletions): New Boolean flag, defaulted to False
	(Delete): Only delete a file if it is writable, and when
	Force_Deletions is True.
	(Parse_Cmd_Line): New switch -f: set Force_Deletions to True
	(Usage): Line for new switch -f
	(Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
	own.

2004-10-26  Eric Botcazou  <ebotcazou@act-europe.fr>

	* decl.c (gnat_to_gnu_field): Use the type of the inner object for a
	JM type only if its size matches that of the wrapper.  When a size is
	prescribed and the field is not aliased, remove the wrapper of a JM
	type only if the size is not greater than that of the packed array.
	(gnat_to_gnu_entity): Change the extension of packed array wrappers
	from LJM to JM.

2004-10-26  Geert Bosch  <bosch@gnat.com>

	* eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
	(Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
	(Pred): Implement in terms of Succ.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* exp_aggr.adb (Safe_Component): An aggregate component that is an
	unchecked conversion is safe for in-place use if the expression of the
	conversion is safe.
	(Expand_Array_Aggregate): An aggregate that initializes an allocator may
	be expandable in place even if the aggregate does not come from source.
	(Convert_Array_Aggr_In_Allocator): New procedure to initialize the
	designated object of an allocator in place, rather than building it
	first on the stack. The previous scheme forces a full copy of the array,
	and may be altogether unsusable if the size of the array is too large
	for stack allocation.

2004-10-26  Robert Dewar  <dewar@gnat.com>

	* exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
	compares if the component is atomic.

	* exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
	array assignment if the component type is atomic.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>
	    Eric Botcazou  <ebotcazou@act-europe.fr>

	* exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
	is aliased and is a by_reference type, do not pass by copy.
	(Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
	detect whether the call is in the right side of an assignment or
	the expression of an object declaration.  Recurse on component
	association within aggregates.
	Call it in the condition that determines whether the temporary is
	necessary for correct stack-checking.

2004-10-26  Thomas Quinot  <quinot@act-europe.fr>

	* exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
	RACW_Type, used in the PolyORB version.
	Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
	version and the GARLIC version.

	* snames.ads, snames.adb, s-parint.ads, s-parint.adb:
	Rename RCI_Info to RCI_Locator for better consistency between the
	GARLIC and PolyORB versions of the distributed systems annex.
	(DSA_Implementation_Name): This enumeration lists the possible
	implementations of the Partition Communication Subsystem for the
	Distributed Systems Annex (DSA). The three available implementations
	are the dummy stub implementation (No_DSA), and two versions based on
	two different distribution runtime libraries: GARLIC and PolyORB. Both
	the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
	technology.
	Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
	that organization.

	* rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
	between the GARLIC and PolyORB versions of the distributed systems
	annex.
	Remove RE_Unbounded_Reclaim_Pool since it is unused.

2004-10-26  Gary Dismukes  <dismukes@gnat.com>

	* gnat1drv.adb: Suppress calling the back end when
	Frontend_Layout_On_Target is true.

2004-10-26  Thomas Quinot  <quinot@act-europe.fr>

	* g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
	Set_Read_Only): New subprograms.
	These new routines allow the user to set or unset the Owner execute
	and Owner write permission flags on a file.

	* makegpr.adb, mlib.adb, mlib-prj.adb: Use
	GNAT.OS_Lib.Set_Executable instead of rolling our own.

2004-10-26  Matthew Gingell  <gingell@gnat.com>

	* i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.

2004-10-26  Pascal Obry  <obry@gnat.com>

	* init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
	memory before the faulting page we properly test the process read
	access for this address using appropriate Win32 routine.
	(HPUX sections): guard with "__hpux__" instead of "hpux".

2004-10-26  Robert Dewar  <dewar@gnat.com>

	* lib-xref.adb (Generate_Reference): Don't complain about reference to
	entry parameter if pragma Unreferenced set, since we do not properly
	handle the case of multiple parameters.

2004-10-26  Vincent Celier  <celier@gnat.com>

	* prj-env.adb: (Contains_ALI_Files): New Boolean function
	(Ada_Objects_Path.Add): For a library project, add to the object path
	the library directory only if there is no object directory or if the
	library directory contains ALI files.
	(Set_Ada_Paths.Add.Recursive_Add): Ditto

2004-10-26  Vincent Celier  <celier@gnat.com>

	* prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
	extension of library projects.

	* prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
	path defaults to ".:<prefix>/lib/gnat".
	(Parse): For an extending all project, allow direct import of a project
	that is virtually extended.

	* prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
	the specified name is directly imported, return its ID. Otherwise, if
	an extension of this project is imported, return the ID of the
	extension.

2004-10-26  Robert Dewar  <dewar@gnat.com>

	* s-arit64.adb: (Le3): New function, used by Scaled_Divide
	(Sub3): New procedure, used by Scaled_Divide
	(Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
	correct more than one instance of failure to propagate carries
	correctly.
	(Double_Divide): Handle overflow case of largest negative number
	divided by minus one.

	* s-arit64.ads (Double_Divide): Document that overflow can occur in
	the case of a quotient value out of range.
	Fix comments.

2004-10-26  Robert Dewar  <dewar@gnat.com>

	* s-bitops.adb (Bit_Eq): Remove redundant check.

	* s-bitops.ads: Minor comment updates
	Change some occurrences of Address to System.Address

	* s-carsi8.ads: Fix minor cut-and-paste error in comments

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
	accessibility check to prefix that is a protected operation.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch10.adb (Optional_Subunit): If file of expected subunit is
	empty, post message on stub.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>
	    Javier Miranda  <miranda@gnat.com>

	* sem_ch12.adb (In_Main_Context): Predicate to determine whether the
	current instance appears within a unit that is directly in the context
	of the main unit.
	Used to determine whether the body of the instance should be analyzed
	immediately after its spec, to make its subprogram bodies available
	for front-end inlining.
	(Analyze_Formal_Array_Type): Cleanup condition that checks that range
	constraint is not allowed on the component type (AARM 12.5.3(3))

2004-10-26  Cyrille Comar  <comar@act-europe.fr>

	* sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
	'Storage_Pool): enhance, document & limit detection of non-sharable
	internal pools.

	* impunit.adb: Make System.Pool_Global and System.Pool_Local visible.

	* s-pooglo.ads: Add more documentation now that this pool is properly
	documented.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
	or protected type with discriminants, do not constrain the
	corresponding record type if the subtype declaration has no
	discriminant constraints. This can be the case in source code, or in
	the subtype declaration created to rename an actual type within an
	instantiation.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
	different kind of stub (possibly wrong name for file), do not check
	for conformance.
	(Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
	includes call to some function that returns an unconstrained type, do
	not inline.

2004-10-26  Ed Schonberg  <schonberg@gnat.com>

	* sem_elab.adb (Check_Elab_Call): Do not check a call that does not
	appear in the code for the main unit. Dependencies among units in the
	context of the main unit are established when those other units are
	compiled. Otherwise spurious elaboration constraints can generate
	incorrect elaboration circularities.

2004-10-26  Thomas Quinot  <quinot@act-europe.fr>
	    Ed Schonberg   <schonberg@gnat.com>

	* sem_util.adb (Is_Aliased_View): Defend against the case where this
	subprogram is called with a parameter that is not an object name. This
	situation arises for some cases of illegal code, which is diagnosed
	later, and in this case it is wrong to call Is_Aliased, as that might
	cause a compiler crash.
	(Explain_Limited_Type): Refine previous fix to include
	inherited components of derived types, to provide complete information.

	* exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
	is the prival for a protected object.
	It is necessary to mark this entity as a variable, in addition to
	flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
	modified to avoid checking the Aliased flag on entities that are not
	objects. (Checking that flag for non-objects is erroneous and could
	lead to a compiler crash).

2004-10-26  Robert Dewar  <dewar@gnat.com>

	* s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
	X_Frac = 0.5, then we know that the number X must be positive.
	(Succ): Remove the same redundant test, and also fix the primary test
	to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
	Minor reformatting
	(Decompose): Add fuller comments to spec

2004-10-26  Pascal Obry  <obry@gnat.com>

	* tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
	validity (process must have read access). Set to 0 in all other cases.
	(STOP_FRAME): Now check for ptr validity to avoid a segmentation
	violation on Win32.
	(VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
	segmentation violation.

2004-10-26  Eric Botcazou  <ebotcazou@act-europe.fr>

	* trans.c (call_to_gnu): For an (in-)out parameter passed by reference
	whose type is a constructed subtype of an aliased object with an
	unconstrained nominal subtype, convert the actual to the constructed
	subtype before taking its address.

2004-10-26  Vincent Celier  <celier@gnat.com>

	* a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
	(Is_Path_Name_Case_Sensitive): New function

	* a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
	(Base_Name, Simple_Name, Current_Directory, Compose,
	Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
	the result.

2004-10-26  Cyrille Comar    <comar@act-europe.fr>
	    Vasiliy Fofanov  <fofanov@act-europe.fr>
	    Vincent Celier   <celier@gnat.com>

	* gnat_ugn.texi: Generalize "finding memory problems" section into a
	"memory management issues" section and document some of the useful
	memory pools provided as part of the GNAT library.
	Remove "virtual" from declaration of A::method2 in
	the simple example of Ada/C++ mixed system.
	Library Projects may be virtually extended: their virtual extensions
	are not Library Projects.
	Added section on extending project hierarchies.

2004-10-19  Aaron W. LaFramboise  <aaronavay62@aaronwl.com>

	* adaint.c (__gnat_get_libraries_from_registry): Cast value
	to LPBYTE.
	(__gnat_portable_spawn): Remove const.

2004-10-17  Matthias Klose  <doko@debian.org>

	* gnatvsn.ads: Set gnat library version to 4.0.

2004-10-05  Vincent Celier  <celier@gnat.com>

	* tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
	other x86 platforms).

2004-10-04  Olivier Hainque  <hainque@act-europe.fr>

	* s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
	in general and triggers stack alignment adjustment for thread entry
	points on targets where this is necessary.

2004-10-04  Bernard Banner  <banner@gnat.com>

	PR ada/13897
	* Makefile.in: Add section for powerpc linux
	Add variant i-vxwork-x86.ads

	* i-vxwork-x86.ads, system-linux-ppc.ads: New files.

2004-10-04  Olivier Hainque  <hainque@act-europe.fr>

	* init.c (__gnat_initialize): Call an Ada subprogram to perform the
	table registration calls when need be. Ensures no reference to the crt
	ctors symbol are issued in the SJLJ case, which avoids possible
	undefined symbol errors in the case of modules to be statically linked
	with the kernel.

2004-10-04  Javier Miranda  <miranda@gnat.com>

	* sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
	in-line the code corresponding to subprogram Analyze_Actuals. In
	addition, analyze the actuals only in case of subprogram call.

2004-10-04  Ed Falis  <falis@gnat.com>

	* s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size

2004-10-04  Sergey Rybin  <rybin@act-europe.fr>

	* g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
	in the documentation.

2004-10-04  Robert Dewar  <dewar@gnat.com>

	* sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
	IF and CASE.
	(Analyze_Block_Statement): Add circuitry to detect following dead code

2004-10-04  Robert Dewar  <dewar@gnat.com>

	* g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
	(XMatchD): Avoid warning for Logic_Error call

2004-10-04  Robert Dewar  <dewar@gnat.com>

	* exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
	consider expressions buried within a procedure actual to be an actual.
	This caused some blowups with uses of packed slices within a procedure
	actual.

2004-10-04  Robert Dewar  <dewar@gnat.com>

	* exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
	longer need to be initialized to zero.
	(Get_Simple_Init_Val): Modular packed arrays no longer need to be
	initialized to zero.

	* checks.adb (Expr_Known_Valid): Packed arrays are now always
	considered valid, even if the representation is modular. That's correct
	now that we no longer initialize packed modular arrays to zero.

	* exp_dbug.ads: Clarify documentation on handling of PAD and JM
	suffixes. These are now documented as the only cases in which the
	debugger ignores outer records.
	Previously, the spec allowed arbitrary suffixes for this purpose.
	Change name of LJM to JM for packed array pad records
	Create separate section on packed array handling, and add a whole new
	set of comments to this section describing the situation with packed
	modular types and justification requirements depending on endianness.

2004-10-04  Robert Dewar  <dewar@gnat.com>

	* a-except.adb: Add a comment for last change

	* einfo.ads: Minor spelling correction in comment

	messages.

	* sem_util.ads: Minor comment update

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
	Inline_Always when in Configurable_Run_Time mode.

	* sem_prag.adb (Process_Convention): If entity is an inherited
	subprogram, apply convention to parent subprogram if in same scope.
	(Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
	when in Configurable_Run_Time mode.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
	class_wide type after component list has been inherited.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch12.adb (Check_Generic_Actuals): New predicate
	Denotes_Previous_Actual, to handle properly the case of a private
	actual that is also the component type of a subsequent array actual.
	The visibility status of the first actual is not affected when the
	second is installed.
	(Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
	make fully recursive the treatment of formals of packages declared
	with a box.
	(Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
	the above on exit from an instantiation.
	(Denotes_Formal_Package): When called from Restore_Private_Views, ignore
	current instantiation which is now complete.
	(Analyze_Package_Instantiation): No instantiated body is needed if the
	main unit is generic. Efficient, and avoid anomalies when a instance
	appears in a package accessed through rtsfind.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

	* exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
	do not generate a declaration for a temporary if the call is part of a
	library-level instantiation.

2004-10-04  Ed Schonberg  <schonberg@gnat.com>

	* sem_util.adb (Explain_Limited_Type): Ignore internal components when
	searching for a limited component to flag.

	* exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
	expansion of Input, to account for the fact that the implicit call
	generated by the attribute reference must freeze the user-defined
	stream subprogram. This is only relevant to 'Input, because it can
	appear in an object declaration, prior to the body of the subprogram.

	* sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
	expansion can proceed and further errors uncovered.
	(Minor clean up): Fix cases of using | instead of \ for continuation
	messages.

2004-10-04  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

	* cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.

	* a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
	in file name.
	(Is_Valid_Path_Name): Take '/' as a directory separator.

2004-10-04  Vincent Celier  <celier@gnat.com>

	assertion error.
	(Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
	resolved path.
	(Parse_Single_Project): Ditto.

	* prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
	Add_To_Project_Path for virtual projects.

	default anymore.

	* makegpr.adb (Get_Imported_Directories.add): Remove trailing
	directory separator, if any.
	(Gprmake): Do not allow mains on the command line for library projects.
	Do not attempt to link when the project is a library project.
	(Library_Opts): New table to store Library_Options.
	(Build_Library): If Library_Options is specified, pass these options
	when building a shared library.

2004-10-04  Jose Ruiz  <ruiz@act-europe.fr>

	* s-tposen.adb (Service_Entry): The object must be always unlocked at
	the end of this procedure now that the unlock operation was inserted
	by the expander.

2004-10-04  Jose Ruiz  <ruiz@act-europe.fr>

	* targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
	corresponding to the Preallocated_Stacks flags in System.

	system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
	system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
	used to signal whether the compiler creates the required stacks and
	descriptors for the different tasks (when True) or it is done by the
	underlying operating system at run time (when False).
	It is initially set to False in all targets.

	* exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
	if it is supported by the target.
	(Make_Task_Create_Call): Pass the stack address if it has been
	previously created. Otherwise pass a Null_Address.

	* snames.adb: Add _stack.

	* snames.ads: Add Name_uStack. Required to allow the expander to
	statically allocated task stacks.

	* s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
	Stack_Address argument.
	Check that its value is equal to Null_Address because this target does
	not support the static stack allocation.

2004-10-04  Thomas Quinot  <quinot@act-europe.fr>

	* usage.adb: Change "pragma inline" to "pragma Inline" in information
	and error messages

2004-10-04  Thomas Quinot  <quinot@act-europe.fr>

	* exp_dist.adb: Split declaration of asynchronous flag out of
	Add_RACW_Read_Attribute.
	Minor reformatting for better alignment with PolyORB version.
	Store the entity for the asynchronous flag of an RACW, rather than the
	expression, in the asynchronous flags table. This will allow this flag
	to be used in other subprograms beside Add_RACW_Read_Attribute.

2004-10-04  Thomas Quinot  <quinot@act-europe.fr>

	* g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

	g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
	g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
	g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads:  Add new
	sockets constant MSG_NOSIGNAL (Linux-specific).
	Add new sockets constant MSG_Forced_Flags, list of flags to be set on
	all Send operations.
	For Linux, set MSG_NOSIGNAL on all send operations to prevent them
	from trigerring SIGPIPE.
	Rename components to avoid clash with Ada 2005 possible reserved
	word 'interface'.
	(Check_Selector): When the select system call returns with an error
	condition, propagate Socket_Error to the caller.

2004-10-01  Jan Hubicka  <jh@suse.cz>

	* misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

2004-09-23  Robert Dewar  <dewar@gnat.com>

	PR ada/17540
	* sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
	instead do this at freeze time (we won't do it if there is an address
	clause).
	Change "pragma inline" to "pragma Inline" in information and error
	messages.
	Minor reformatting.

	* freeze.adb (Check_Address_Clause): Remove previous change, not the
	right way of doing things after all.
	(Freeze_Entity): For object, set Is_Public for imported entities
	unless there is an address clause present.

2004-09-21  Olivier Hainque  <hainque@act-europe.fr>

	* decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
	dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
	ensures proper handling of types with rep clauses, which might have
	their TYPE_SIZE set already.

2004-09-21  Robert Dewar  <dewar@gnat.com>

	* decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
	packed array types in both little- and big-endian cases. This change
	ensures that we no longer count on the unused bits being initialized
	for such types (and in particular ensures that equality testing will
	only read the relevant bits).
	Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
	These changes mean that we no longer need to initialize small packed
	arrays.
	(gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
	optimization to an LJM field as to its parent field.

	* ada-tree.h, trans.c, utils.c, utils2.c:
	Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P

2004-09-20  Jan Hubicka  <jh@suse.cz>

	* utils.c (gnat_finalize): Remove.
	(end_subprog_body): Directly call cgraph_finalize_function;
	do not lower the nested functions.

2004-09-20  Robert Dewar  <dewar@gnat.com>

	PR ada/17540
	* freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
	if an address clause is present, since that means that the Import
	should be ignored.

2004-09-20  Arnaud Charlet  <charlet@act-europe.fr>

	* 5tsystem.ads: Removed, no longer used.

2004-09-17  Jeffrey D. Oldham  <oldham@codesourcery.com>
	    Zack Weinberg  <zack@codesourcery.com>

	* ada-tree.def: Use tree_code_class enumeration constants
	instead of code letters.
	* ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
	Update for new tree-class enumeration constants.

2004-09-17  Vincent Celier  <celier@gnat.com>

	* prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private

2004-09-09  Vincent Celier  <celier@gnat.com>

	* a-direct.ads: Add pragma Ada_05
	(Directory_Entry_Type): Give default value to component Kind to avoid

	* a-direct.adb (Current_Directory): Remove directory separator at the
	end.
	(Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
	an existing directory.
	(Fetch_Next_Entry): Give default value to variable Kind to avoid warning
	(Size (String)): Function C_Size returns Long_Integer, not File_Size.
	Convert the result to File_Size.

	* prj.ads: (Project_Error): New exception

	* prj-attr.adb: Except in procedure Initialize, Fail comes from
	Prj.Com, not from Osint.
	(Attrs, Package_Attributes): Tables moved to private part of spec
	(Add_Attribute, Add_Unknown_Package): Moved to new child package
	Prj.Attr.PM.
	(Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
	Prj.Project_Error after call to Fail.
	(Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
	Fail. Check that package name is not already in use.

	* prj-attr.ads: Comment updates to indicate that all subprograms may be
	used by tools, not only by the project manager, and to indicate that
	exception Prj.Prj_Error may be raised in case of problem.
	(Add_Unknown_Package, Add_Attribute): Moved to new child package
	Prj.Attr.PM.
	(Attrs, Package_Attributes): Table instantiations moved from the body to
	the private part to be accessible from Prj.Attr.PM body.

	* prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
	from new package Prj.Attr.PM.
	(Parse_Attribute_Declaration): Call Add_Attribute from new package
	Prj.Attr.PM.

	raise Program_Error if called from a protected operation.

	* s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
	the protected action nesting level.
	(Lock_Read_Only): When pragma Detect_Blocking is active increase the
	protected action nesting level.
	(Unlock): When pragma Detect_Blocking is active decrease the protected
	action nesting level.

	* s-taskin.adb (Initialize_ATCB): Initialize to 0 the
	Protected_Action_Nesting.

	* s-taskin.ads: Adding the field Protected_Action_Nesting to the
	Common_ATCB record. It contains the dynamic level of protected action
	nesting for each task. It is needed for checking whether potentially
	blocking operations are called from protected operations.
	(Detect_Blocking): Adding a Boolean constant reflecting whether pragma
	Detect_Blocking is active or not in the partition.

	* s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
	raise Program_Error if called from a protected operation.
	(Task_Entry_Call): When pragma Detect_Blocking is active, raise
	Program_Error if called from a protected operation.
	(Timed_Task_Entry_Call): When pragma Detect_Blocking is active, raise
	Program_Error if called from a protected operation.

	* s-tassta.adb (Abort_Tasks): When pragma Detect_Blocking is active,
	raise Program_Error if called from a protected operation.

	(Unlock_Entry): When pragma Detect_Blocking is active decrease the
	protected action nesting level.

	* sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
	insertion of the statement raising Program_Error. The run time
	contains the required machinery for handling that.

	* sem_util.ads: Change comment associated to procedure
	Check_Potentially_Blocking_Operation.
	This procedure does not insert a call for raising the exception because
	that is currently done by the run time.

	* raise.h (__gnat_set_globals): Pass the detect_blocking parameter.

	* init.c: Add the global variable __gl_detect_blocking that indicates
	whether pragma Detect_Blocking is active (1) or not (0). Needed for

	* lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
	pragma Detect_Blocking is active.

	* lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.

	* ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
	DB is found in the ali file. Any unit compiled with pragma
	Detect_Blocking active forces its effect in the whole partition.

	* a-retide.adb (Delay_Until): Raise Program_Error if pragma
	Detect_Blocking is active and delay is called from a protected
	operation.

	* bindgen.adb (Gen_Adainit_Ada): When generating the call to
	__gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
	Detect_Blocking is active (0 otherwise).
	(Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
	as Detect_Blocking parameter if pragma Detect_Blocking is active (0
	otherwise).

2004-09-09  Thomas Quinot  <quinot@act-europe.fr>

	* gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
	GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
	package.

	* s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
	(Register_Receiving_Stub): Add Subp_Info formal parameter.
	Update API in placeholder implemetation of s-parint to reflect changes
	in distribution runtime library.

	* sem_ch3.adb (Expand_Derived_Record): Rename to
	Expand_Record_Extension.

	* sem_disp.adb (Check_Controlling_Formals): Improve error message for
	primitive operations of potentially distributed object types that have
	non-controlling anonymous access formals.

	* sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
	subprogram.
	New implementation of expansion for remote access-to-subprogram types,
	based on the RACW infrastructure.
	This version of sem_dist is compatible with PolyORB/DSA as well as
	GLADE.

	* sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
	Asynchrronous that applies to a remote access-to-subprogram type, mark
	the underlying RACW type as asynchronous.

	* link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
	 __gnat_using_gnu_linker to 1.

	* Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
	g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
	GNAT.Perfect_Hash_Generators, and remove the empty
	GNAT.Perfect_Hash package.

	* atree.adb: Minor reformatting

	* exp_ch3.adb (Expand_Derived_Record): Rename to
	Expand_Record_Extension.
	(Build_Record_Init_Proc.Build_Assignment): The default expression in
	a component declaration must remain attached at that point in the
	tree so New_Copy_Tree copies it if the enclosing record type is derived.
	It is therefore necessary to take a copy of the expression when building

	includes case of a variable referenced on the left hand side of an
	assignment, therefore remove redundant code. Variables and prefixes of

	hand side. Warnings are now properly emitted when variables or prefixes
	are assigned but not read.

	"variable ... is assigned but never read" since other entities may read
	the memory location.

	routine to insert conversions when needed, and complete resolution of
	node.
	(Resolve_Intrinsic_Operator): Fix cut-and-paste bug on transfer of
	interpretations for rewritten right operand.
	(Set_Mixed_Mode_Operand): Handle properly a universal real operand when

	discriminated type is not referenced.

	* lib-xref.adb (Generate_Reference): A deferred constant completion,
	record representation clause or record type discriminant does not
	produce a reference to its corresponding entity. Warnings are now

	* a-numaux-x86.adb (Reduce): Reimplement using an approximation of Pi
	with 192 bits of precision, sufficient to reduce a double-extended
	arguments X with a maximum relative error of T'Machine_Epsilon, for X
	in -2.0**32 .. 2.0**32.
	(Cos, Sin):  Always reduce arguments of 1/4 Pi or larger, to prevent

	warning over '<pointer> is never assigned a value'.

	executable name when not initialized. Otherwise, use its current value.

	* osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
	initialize it to another executable name than the current one. This
	allows to configure paths for an executable name (gnatmake) different
	from the current one (gnatdist).

2004-03-29  Ed Schonberg  <schonberg@gnat.com>

	* exp_ch6.adb (Expand_Call): A call to a function declared in the
	current unit cannot be inlined if it appears in the body of a withed
	unit, to avoid order of elaboration problems in gigi.

	* exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
	information for protected (wrapper) operation as well, to simplify gdb
	use.

	* sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

	* sem_prag.adb (Process_Convention): If subprogram is overloaded, only
	apply convention to homonyms that are declared explicitly.

	that renames an equality operator and the operands are overloaded,
	resolve them with the declared formal types, before rewriting as an

	Resolve links only when not in Trusted_Mode.
	(Find_Sources, Recursive_Find_Dirs, Find_Source_Dirs, Locate_Directory):
	Do not resolve links for the display names.

	* prj-part.adb (Parse_Single_Project, Project_Path_Name_Of): Do not
	resolve links when computing the display names.

2004-03-25  Thomas Quinot  <quinot@act-europe.fr>

	* sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
	attribute reference does not denote a subtype, it can be any
	expression that has a classwide type, potentially after an implicit
	dereference.  In particular, the prefix can be a view conversion for
	a classwide type (for which Is_Object_Reference holds), but it can
	also be a value conversion for an access-to-classwide type. In the
	latter case, there is an implicit dereference, and the original node
	for the prefix does not verify Is_Object_Reference.

	* sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
	conversion of a discriminant-dependent component of a mutable object
	is one itself.

2004-03-25  Ed Schonberg  <schonberg@gnat.com>

	* freeze.adb (Freeze_Entity): When an inherited subprogram is
	inherited, has convention C, and has unconstrained array parameters,
	place the corresponding warning on the derived type declaration rather
	than the original subprogram.

	* sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
	indication on renaming declaration, if formal has a box and actual
	is absent.

	* sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
	determine whether to generate an implicit or explicit reference to
	the renamed entity.

	* sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
	subprogram renaming comes from a defaulted formal subprogram in an
	instance.

2004-03-25  Gary Dismukes  <dismukes@gnat.com>

	* sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
	value expressions to ensure that calls within a component definition
	will be checked (since those are evaluated during the record type's
	elaboration).

2004-03-25  Arnaud Charlet  <charlet@act-europe.fr>

	* s-tpobop.adb: Code clean up:
	(Requeue_Call): Extract from PO_Service_Entries to remove duplicated

	declaration for a child subprogram body that acts as a spec, indicate
	that the entity in the declaration needs debugging information.

	* sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
	full view if the subtype is created for a constrained record component;
	gigi has enough information to construct the record, and there is no
	place in the tree for the declaration.

	* sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
	serial number for the dummy body that is built for analysis, to avoid
	inconsistencies in the generation of internal names when compiling
	with -gnatN.

2004-03-22  Thomas Quinot  <quinot@act-europe.fr>

	* ada-tree.h: Update copyright notice.
	Minor reformatting.

2004-03-19  Olivier Hainque  <hainque@act-europe.fr>

	* decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
	as regular exception objects and not as mere integers representing the
	condition code.  The latter approach required some dynamics to mask off
	severity bits, which did not fit well into the GCC table based model.
	(gnat_to_gnu_entity, objects): Don't supply an external name for VMS
	exception data objects. We don't it and it would conflict with the other
	external symbol we have to generate for such exceptions.

	* trans.c (tree_transform, case N_Exception_Handler): Remove part of
	the special code for VMS exceptions, since these are now represented
	as regular exceptions objects.

2004-03-19 Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

2004-03-18  Thomas Quinot  <quinot@act-europe.fr>

	* adaint.c: Update comments.

	* Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
	GNATLIB_SHARED for FreeBSD.

2004-03-18  Jose Ruiz  <ruiz@act-europe.fr>

	* init.c [VxWorks]: Do not fix the stack size for the environment task.
	When needed (stack checking) the stack size is retrieved
	from the VxWorks kernel.

	* Makefile.in: Flag -nostdinc is required when building the run time
	for avoiding looking for files in the base compiler.
	Add the VxWorks specific version of the package body for
	System.Stack_checking.Operations (5zstchop.adb).

	* Make-lang.in: Add the object file for
	System.Stack_Checking.Operations.

	* Makefile.rtl: Add object file for the package
	System.Stack_Checking.Operations.

	* s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.

	* s-stache.ads, s-stache.adb: Move the operations related to stack
	checking from this package to package System.Stack_Checking.Operations.
	This way, stack checking operations are only linked in the final
	executable when using the -fstack-check flag.

2004-03-18  Doug Rupp  <rupp@gnat.com>

	* Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

	making sure that each directory is present only once and, for object
	dirs, when a directory already present is added, the duplicate is
	removed and the directory is always put as the last in the table.
	Write the path files at the end of these accumulations.

	* prj-nmsc.adb (Record_Source): Add source file name in hash table
	Files_Htable for all sources.

	* a-ngcoty.adb (Modulus): In alternate formula for large real or
	imaginary parts, use Double precision throughout.

	* a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
	we want to be able to compile run-time with -gnata for testing, but
	this may also be instantiated in user code that is compiled with -gnata.

2004-03-15  Olivier Hainque  <hainque@act-europe.fr>

	* s-stalib.ads (Exception_Code): New type, to represent Import/Export
	codes. Having a separate type for this is useful to enforce consistency
	throughout the various run-time units.
	(Exception_Data): Use Exception_Code for Import_Code.

	* s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of

	* raise.c (_GNAT_Exception structure): Remove the handled_by_others
	component, now reflected by an exported accessor.
	(is_handled_by): New routine to compute whether the propagated
	occurrence matches some handler choice specification. Extracted out of
	get_action_description_for, and expanded to take care of the VMS
	specifities.
	(get_action_description_for): Use is_handled_by instead of an explicit
	complex condition to decide if the current choice at hand catches the
	propagated occurrence.

	* raise.h (Exception_Code): New type for C.

	* rtsfind.ads (RE_Id, RE_Unit_Table): Add
	System.Standard_Library.Exception_Code, to allow references from the

	New accessors to allow easy access to GNAT exception data
	characteristics.
	(GNAT_GCC_Exception record, Propagate_Exception): Get rid of the

	routine which will now be able to call the appropriate exception data
	accessor instead.

	* cstand.adb (Create_Standard): Adjust the type of the Import_Code
	component of Standard_Exception_Type to be the closest possible to
	Exception_Code in System.Standard_Library, that we cannot get at this
	point. Expand a ??? comment to notify that this type node should
	probably be rewritten later on.

	registration call to include a pointer to the exception object in the
	arguments.

	* init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In

	* g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.

	* make.adb (Gnatmake): Do not check the executable suffix; it is being
	taken care of in Scan_Make_Arg.
	(Scan_Make_Arg): Add the executable suffix only if the argument
	following -o, in canonical case, does not end with the executable
	suffix.  When in verbose mode and executable file name does not end
	with executable suffix, output the executable name, in canonical case.

	* s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
	to avoid warnings when instantiating Ada.Task_Attributes.
	Minor reformating.

	* mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries

	when looking for user-defined equality operation.

	* exp_ch4.adb (Expand_Composite_Equality): Check that return type is
	boolean when locating primitive equality of tagged component.

	bit-aligned field and the right-hand side a string literal, introduce
	a temporary before expanding assignment into a loop.

	* exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
	priority in full, to ensure that any expanded subepxressions of it are
	elaborated in the scope of the init_proc.

	* exp_prag.adb (Expand_Pragma_Import): Search for initialization call
	after object declaration, skipping over code that may have been
	generated for validity checks.

	* sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
	discriminants, ignore the known discriminants of its full view, if
	any, to check legality.

	component if type has unknown discriminants.
	(Analyze_Private_Extension_Declaration): Discriminant constraint is

	* exp_ch4.adb (Expand_N_Indexed_Component): Do not call
	Insert_Dereference_Action when rewriting an implicit dereference into
	an explicit one, this will be taken care of during expansion of the
	explicit dereference.
	(Expand_N_Slice): Same. Always do the rewriting, even for the case
	of non-packed slices, since the dereference action generated by
	expansion of the explicit dereference is needed in any case.
	(Expand_N_Selected_Component): When rewriting an implicit dereference,
	analyze and resolve the rewritten explicit dereference so it is seen
	by the expander.
	(Insert_Dereference_Action): This procedure is now called only for the
	expansion of an N_Explcit_Dereference_Node. Do insert a check even for
	dereferences that do not come from source (including explicit
	dereferences resulting from rewriting implicit ones), but do not
	recursively insert a check for the dereference nodes contained within
	the check.

	Minor reformatting and code clean ups.
	Minor changes to prevent -gnatwa warnings

	* ali.adb: Minor reformatting and cleanup of code
	Acquire new SS indication of secondary stack use from ali files

	* a-numaux.ads: Add Pure_Function pragmas for all imported functions
	(since now we expect this to be done for imported functions)

	* bindgen.adb: Generate call to modify default secondary stack size if
	-Dnnn switch given

	* bindusg.adb: Add line for new -D switch

	* exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
	replacement name for Type_May_Have_Non_Bit_Aligned_Components!
	Add circuitry for both records and arrays to avoid gigi
	processing if the type involved has non-bit-aligned components

	* exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
	N_String_Literal node always references an E_String_Literal_Subtype
	entity. This may not be true in the future.
	(Possible_Bit_Aligned_Component): Move processing of
	Component_May_Be_Bit_Aligned from exp_ch5 to exp_util

	* exp_ch6.adb (Expand_Thread_Body): Pick up
	Default_Secondary_Stack_Size as variable so that we get value modified
	by possible -Dnnn binder parameter.

	(Type_May_Have_Bit_Aligned_Components): New function.

	* exp_util.ads (Component_May_Be_Bit_Aligned): New function.

	Minor reformatting.

	* freeze.adb (Freeze_Entity): Add RM reference to error message about
	importing constant atomic/volatile objects.
	(Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
	unless explicit Pure_Function pragma given, to avoid insidious bug of
	call to non-pure imported function getting eliminated.

	* gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb,
	gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,

	so that it can be modified by the new -Dnnn bind switch.

	* rtsfind.adb (Load_Fail): Give full error message in configurable

	of a file not found, which was an oversight.
	Note if secondary stack unit is used by compiler.

	* sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
	ineffective elaborate all pragmas on non-visible packages (this
	happened when a renamed subprogram was called). Now the elaborate all
	always goes on the package containing the renaming rather than the one
	containing the renamed subprogram.

	has an Etype that references an E_String_Literal.
	(Eval_String_Literal): Avoid assumption that N_String_Literal node
	always references an E_String_Literal_Subtype entity. This may not
	be true in the future.

	* sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
	pragma location.

	* sem_res.adb (Resolve): Specialize msg for function name used in proc

	of Item_Name).

	* make.adb (Gnatmake): Special process for files to compile/check when

	Main of the project file and -B is not specified. Do not skip bind/link
	steps when -B is specified.

	library naming scheme.

	* mlib-prj.adb (Build_Library): Generate different names for the static
	or dynamic version of the GNAT runtime. This is needed to support the
	new shared library naming scheme.
	(Process_Binder_File): Add detection of shared library in binder file
	based on the new naming scheme.

	* gnatlink.adb (Process_Binder_File): Properly detect the new naming
	scheme for the shared runtime libraries.

2004-01-05  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
	protected objects when allocator has a subtype indication, not a
	qualified expression. Note that qualified expressions may have to be
	checked when limited aggregates are implemented.

	* sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
	pure, emit warning.
	(Analyze_Pragma, case Pure_Function): If enclosing package is pure and

	standard linker options to get standard libraries linked. We now plan
	to provide dummy versions of these libraries to match the appropriate
	configurable run-time (e.g. if a library is not needed at all, provide
	a dummy empty library).

	* targparm.ads: Configurable_Run_Time mode no longer affects linker
	options (-L parameters and standard libraries). What we plan to do is

2003-12-08  Javier Miranda  <miranda@gnat.com>

	* exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

	are not supported. Add new formal to pass the component type (Ctype).
	It is required to call the corresponding IP subprogram in case of
	default initialized components.
	(Gen_Assign): In case of default-initialized component, generate a
	call to the IP subprogram associated with the component.
	(Build_Record_Aggr_Code): Remove the aggregate from the parent in case
	of aggregate with default initialized components.

	all the present expressions.

	* exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
	to indicate that the initialization call corresponds to a
	default-initialized component of an aggregate.
	In case of default initialized aggregate with tasks this parameter is
	used to generate a null string (this is just a workaround that must be
	improved later). In case of discriminants, this parameter is used to
	generate a selected component node that gives access to the discriminant
	value.

	* exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
	subprogram, based on Build_Task_Allocate_Block, but adapted to expand
	allocated aggregates with default-initialized components.

	* par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
	the box notation is used in positional aggregates.

2003-12-08  Arnaud Charlet  <charlet@act-europe.fr>

	* sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
	they are automatically generated by Make-lang.in and cause nothing but
	maintenance troubles.

2003-12-05  Thomas Quinot  <quinot@act-europe.fr>

	* 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

	the body of System.Interrupt_Management common to several targets.
	Update copyright notice when appropriate.

	* 52osinte.ads, 5posinte.ads: Define a dummy value for the SA_SIGINFO
	constant.

	* 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
	to ensure that the kernel fills in the interrupted context structure
	before calling a signal handler, which is necessary to be able to
	unwind past it. Update the copyright notice.

2003-12-05  Jerome Guitton  <guitton@act-europe.fr>

	* a-elchha.ads: New file.

	instead of the previous simple checksum algorithm.
	(Time_Stamp_Mismatch): use CRC_Match for comparison.
	(Set_Source_Table): idem.

	* ali-util.ads:
	(Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
	instead of simple checksum.
	(CRC_Match): new function.
	(CRC_Error): new constant.

	* ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
	a CRC now and not a simple checksum. A CRC uses lower-case hex
	letters, fixes ambiguity in parsing.

	* ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
	is what this variable will store.

	* bcheck.adb: Change reference to chechsum in comments by CRC.
	(Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.

	CRC using GNAT.CRC32.

	* gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
	now and not anymore a simple checksum.

	* lib-load.adb: Use Source_CRC instead of Source_Checksum in many

	* types.adb (Hex): Use lowercase for the letter part.

	* types.ads (Get_Hex_String): Returns the hexadecimal representation
	for a word. This is currently used only for CRC. In previous version,
	the checksum was using a representation with all letter being
	upper-case. With the new implementation (using CRC) we do not remove
	the 32th bit of the CRC, so we can have an upper-case starting letter
	in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
	It is ambigous since the CRC was optional and could be followed by
	options like EB, EE. So now this routines uses lower-case letter for
	the hexadecimal representation. Strange enough only lower case letters
	where checked in Scan_ALI (even if this was not a possible case).

	* gnatvsn.ads (Library_Version): changed to 3.15a.

	* s-crc32.ads: Initial version from GNAT.CRC32. This is the version
	for the compiler.

	for the compiler.

	* ali-util.adb: Redo previous change to avoid using word CRC everywhere
	Add 2001 to copyright notice
	(Accumulate_Checksum): Modify to use System.CRC32.

	* ali-util.ads: Redo changes of previous revision to continue to use
	the word Checksum. Add 2001 to copyright notice.

	Keep the change for lower case letters in the checksum.

	* ali.ads: Undo previous change not needed.

	* bcheck.adb: Undo most of previous change, not needed.
